Content-type Builder

Page summary:

The Content-type Builder is a tool for designing content types and components. This documentation gives an overview of the Content-type Builder and covers field options, relations, component usage, and shares data modeling tips.

From the Content-type Builder, accessible via the main navigation of the admin panel, users can create and edit their content types.

Overview​

The Content-type Builder allows the creation and management of content-types, which can be:

  • Collection types: content-types that can manage several entries.
  • Single types: content-types that can only manage one entry.
  • Components: content structure that can be used in multiple collection types and single types. Although they are technically not proper content-types because they cannot exist independently, components are also created and managed through the Content-type Builder, in the same way as collection and single types.

All 3 are displayed as categories in the sub navigation of the Content-type Builder. In each category are listed all content-types and components that have already been created.

Tip

Click the search icon in the Content-type Builder sub navigation to find a specific collection type, single type, or component.

In the Content-type Builder's sub navigation is also displayed a centralised Save button that applies for all content-types and components. Along with the display of statuses for both content-types/components and fields, this allows you to work on several content-types and components at the same time. The following statuses can be displayed:

  • New or N indicates that a content-type/component or field is new and hasn't been saved yet,
  • Modified or M indicates that a content-type/component or field has been modified since the last save,
  • Deleted or D indicates that a content-type/component or field has been deleted but that it will only be confirmed once saved.
Note

Clicking on the ... button next to Save gives access to other options, such as Undo/Redo last change and Discard all changes. These options are also centralised, meaning that they apply to the last action(s) that was/were done on all content-types, components and fields since the last time you saved.

Usage​


Creating content-types​

The Content-type Builder allows to create new content-types: single and collection types, but also components.

Creating content-types with Strapi AI NewThis content is new.​

GrowthThis feature is available with a Growth plan.

When enabled, Strapi AI adds an assistant that helps you create or edit content types with natural language.

To use Strapi AI with the Content-Type Builder, click on the button in the bottom right corner of the admin panel, and describe what you need:

Strapi AI in Content-Type BuilderStrapi AI in Content-Type Builder

You can also use the button at the bottom of the chat window to import code from an existing Strapi or front-end application, import a Figma project, or attach an image to extract the content structure from a design.

Tip

The more precise your prompts, the more accurate your created schemas are likely to be.

For example, the following prompt example works well when creating relations: Could you please generate a collection of dogs then also generate an owner collection and add relationship to dogs? An owner can have multiple dogs, but a dog can only have one owner.

Strapi AI credits

Strapi AI includes 1,000 credits per month on the Growth plan, and 10 free credits during the free trial. Lightweight actions use fewer credits, while more complex ones use more.

You can check your credit usage in the Settings Overview of the admin panel. Notifications are sent when your usage reaches 80%, 90%, and 100% of your monthly allowance.

When your credits run out on the Growth plan, you can keep using Strapi AI, with overages billed monthly.

For more information about Strapi AI, please refer to the dedicated support article.

Creating content-types manually​

Content-type creationContent-type creation
  1. Choose whether you want to create a collection type or a single type.
  2. In the Content-type Builder's category of the content-type you want to create, click on Create new collection/single type.
  3. In the content-type creation window, write the name of the new content-type in the Display name textbox.
  4. Check the API ID to make sure the automatically pre-filled values are correct. Collection type names are indeed automatically pluralized when displayed in the Content Manager. It is recommended to opt for singular names, but the API ID field allows to fix any pluralization mistake.
  5. (optional) In the Advanced Settings tab, configure the available settings for the new content-type:
    Setting nameInstructions
    Draft & publishTick the checkbox to allow entries of the content-type to be managed as draft versions, before they are published (see Draft & Publish).
    InternationalizationTick the checkbox to allow entries of the content-type to be translated into other locales.
  6. Click on the Continue button.
  7. Add and configure chosen fields for your content-type (see Configuring fields for content-types).
  8. Click on the Save button.
Caution

New content-types are only considered created once they have been saved. Saving is only possible if at least one field has been added and properly configured. If these steps have not been done, a content-type cannot be created, listed in its category in the Content-type Builder, and cannot be used in the Content Manager.

New component​

Component creationComponent creation
  1. In the Components category of the Content-type Builder sub navigation, click on Create new component.
  2. In the component creation window, configure the basic settings of the new component:
    • Write the name of the component in the Display name textbox.
    • Select an available category, or enter in the textbox a new category name to create one.
    • (optional) Choose an icon representing the new component. You can use the search to find an icon instead of scrolling through the list.
  3. Click on the Continue button.
  4. Add and configure chosen fields for your component (see Configuring fields for content-types).
  5. Click on the Save button.

Editing content-types​

The Content-type Builder allows to manage all existing content-types. For an chosen content-type or component to edit, the right side of the Content-type Builder interface displays all available editing and management options.

Settings​

  1. Click on the Edit button of your content-type to access its settings.
  2. Edit the available settings of your choice:
Content-type Builder's basic settingsContent-type Builder's basic settings
  • Display name: Name of the content-type or component as it will be displayed in the admin panel.
  • API ID (singular): Name of the content-type or component as it will be used in the API. It is automatically generated from the display name, but can be edited.
  • API ID (plural): Plural name of the content-type or component as it will be used in the API. It is automatically generated from the display name, but can be edited.
  • Type: Type of the content-type or component. It can be either a Collection type or a Single type.
  1. Click the Finish button in the dialog.
  2. Click the Save button in the Content-Type Builder navigation.

Fields​

From the table that lists the fields of your content-type, you can:

  • Click on the button to access a field's basic and advanced settings to edit them
  • Click on the Add another field buttons to create a new field for the selected content-type
  • Click on the button and drag and drop any field to reorder the content-type's fields
  • Click on the button to delete a field
Caution

Editing a field allows renaming it. However, keep in mind that regarding the database, renaming a field means creating a whole new field and deleting the former one. Although nothing is deleted from the database, the data that was associated with the former field name will not be accessible from the admin panel of your application anymore.

Configuring content-types fields​

Content-types are composed of one or several fields. Each field is designed to contain specific kind of data, filled up in the Content Manager (see Creating & Writing content).

In the Content-type Builder, fields can be added at the creation of a new content-type or component, or afterward when a content-type or component is edited or updated.

Note

Depending on what content-type or component is being created or edited, not all fields -including components and dynamic zones- are always available.

Fields selectionFields selection

Text​

The Text field displays a textbox that can contain small text. This field can be used for titles, descriptions, etc.

Setting nameInstructions
NameWrite the name of the Text field.
TypeChoose between Short text (255 characters maximum) and Long text, to allow more or less space to fill up the Text field.

Rich Text (Blocks)​

The Rich Text (Blocks) field displays an editor with live rendering and various options to manage rich text. This field can be used for long written content, even including images and code.

Setting nameInstructions
NameWrite the name of the Rich Text (Blocks) field.
React renderer

If using the Blocks editor, we recommend that you also use the Strapi Blocks React Renderer to easily render the content in a React frontend.

Number​

The Number field displays a field for any kind of number: integer, decimal and float.

Setting nameInstructions
NameWrite the name of the Number field.
Number formatChoose between integer, big integer, decimal and float.

Date​

The Date field can display a date (year, month, day), time (hour, minute, second) or datetime (year, month, day, hour, minute, and second) picker.

Setting nameInstructions
NameWrite the name of the Date field.
TypeChoose between date, datetime and time

Password​

The Password field displays a password field that is encrypted.

Setting nameInstructions
NameWrite the name of the Password field.

Media​

The Media field allows to choose one or more media files (e.g. image, video) from those uploaded in the Media Library of the application.

Setting nameInstructions
NameWrite the name of the Media field.
TypeChoose between Multiple media to allow multiple media uploads, and Single media to only allow one media upload.

Relation​

The Relation field allows to establish a relation with another content-type, that must be a collection type.

There are 6 different types of relations:

  • One way: Content-type A has one Content-type B
  • One-to-one: Content-type A has and belong to one Content-type B
  • One-to-many: Content-type A belongs to many Content-type B
  • Many-to-one: Content-type B has many Content-type A
  • Many-to-many: Content-type A has and belongs to many Content-type B
  • Many way: Content-type A has many Content-type B
Multi relations and single relations

Relations where at least one side can reference several entries are called multi relations. In the Content-type Builder, this includes one-to-many, many-to-one, many-to-many, and many-way relations. These relations appear as multi-select fields in the Content Manager and return arrays from the REST, GraphQL, and Document Service APIs; while single relations (one-way and one-to-one relations) return a single linked entry (see Managing relations with API requests for more information).

Configuring the basic settings of the Relation field consists in choosing with which existing content-type the relation should be established and the kind of relation. The edition window of the Relation field displays 2 grey boxes, each representing one of the content-types in relation. Between the grey boxes are displayed all possible relation types.

  1. Click on the 2nd grey box to define the content-type B. It must be an already created collection type.
  2. Click on the icon representing the relation to establish between the content-types.
  3. Choose the Field name of the content-type A, meaning the name that will be used for the field in the content-type A.
  4. (optional if disabled by the relation type) Choose the Field name of the content-type B.
Modeling nested page hierarchies

To model a navigable tree of pages:

  1. Add a Page collection type with a "Slug" (UID) and (optionally) an "Order" (Integer) field to control sibling ordering.
  2. Create a Relation field from Page to Page and choose Many-to-one so each page can set its "Parent page". Strapi automatically provides the inverse "Children pages" relation.
  3. When reading data, populate children recursively to load the tree. Keep the recursion depth small to avoid large responses.
Example
Populate nested children for a page tree
{
  populate: {
    children: {
      fields: ['title', 'slug'],
      populate: {
        children: {
          fields: ['title', 'slug'],
        },
      },
    },
  },
}

The same populate pattern works with GraphQL or the Document Service API (see Understanding populate guide).

Boolean​

The Boolean field displays a toggle button to manage boolean values (e.g. Yes or No, 1 or 0, True or False).

Setting nameInstructions
NameWrite the name of the Boolean field.

JSON​

The JSON field allows to configure data in a JSON format, to store JSON objects or arrays.

Setting nameInstructions
NameWrite the name of the JSON field.

Email​

The Email field displays an email address field with format validation to ensure the email address is valid.

Setting nameInstructions
NameWrite the name of the Email field.

Password​

The Password field displays a password field that is encrypted.

Setting nameInstructions
NameWrite the name of the Password field.

Enumeration​

The Enumeration field allows to configure a list of values displayed in a drop-down list.

Setting nameInstructions
NameWrite the name of the Enumeration field.
ValuesWrite the values of the enumeration, one per line.
Caution

Enumeration values should always have an alphabetical character preceding any number as it could otherwise cause the server to crash without notice when the GraphQL plugin is installed.

UID​

The UID field displays a field that sets a unique identifier, optionally based on an existing other field from the same content-type.

Setting nameInstructions
NameWrite the name of the UID field. It must not contain special characters or spaces.
Attached fieldChoose what existing field to attach to the UID field. Choose None to not attach any specific field.
Tip

The UID field can be used to create a slug based on the Attached field.

Rich Text (Markdown)​

The Rich Text (Markdown) field displays an editor with basic formatting options to manage rich text written in Markdown. This field can be used for long written content.

Setting nameInstructions
NameWrite the name of the Rich Text (Markdown) field.

Components​

Components are a combination of several fields. Components allow to create reusable sets of fields, that can be quickly added to content-types, dynamic zones but also nested into other components.

When configuring a component through the Content-type Builder, it is possible to either:

  • create a new component by clicking on Create a new component (see Creating a new component),
  • or use an existing one by clicking on Use an existing component.
Setting nameInstructions
NameWrite the name of the component for the content-type.
Select a componentWhen using an existing component only - Select from the drop-down list an existing component.
TypeChoose between Repeatable component to be able to use several times the component for the content-type, or Single component to limit to only one time the use of the component.

Dynamic zones​

Dynamic zones are a combination of components that can be added to content-types. They allow a flexible content structure as once in the Content Manager, administrators have the choice of composing and rearranging the components of the dynamic zone how they want.

Setting nameInstructions
NameWrite the name of the dynamic zone for the content-type.

After configuring the settings of the dynamic zone, its components must be configured as well. It is possible to either choose an existing component or create a new one.

Caution

When using dynamic zones, different components cannot have the same field name with different types (or with enumeration fields, different values).

Custom fields​

Custom fields are a way to extend Strapi’s capabilities by adding new types of fields to content-types or components. Once installed (see Marketplace documentation), custom fields are listed in the Custom tab when selecting a field for a content-type.

Each custom field type can have basic and advanced settings. The Marketplace lists available custom fields, and hosts dedicated documentation for each custom field, including specific settings.

Deleting content-types​

Content types and components can be deleted through the Content-type Builder. Deleting a content-type automatically deletes all entries from the Content Manager that were based on that content-type. The same goes for the deletion of a component, which is automatically deleted from every content-type or entry where it was used.

  1. In the Content-type Builder sub navigation, click on the name of the content-type or component to delete.
  2. In the edition interface of the chosen content-type or component, click on the Edit button on the right side of the content-type's or component's name.
  3. In the edition window, click on the Delete button.
  4. In the confirmation window, confirm the deletion.
  5. Click on the Save button in the Content-type Builder sub navigation.
Caution

Deleting a content-type only deletes what was created and available from the Content-type Builder, and by extent from the admin panel of your Strapi application. All the data that was created based on that content-type is however kept in the database. For more information, please refer to the related GitHub issue.
