Content-type Builder

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

Identity Card of the Content-type Builder

Role & permission: Minimum "Read" permission in Roles > Plugins - Content Type Builder.
Environment: Available in Development environment only.

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: data 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.

Usage

Creating content-types

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

New content-type

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 name	Instructions
   Draft & publish	Tick the checkbox to allow entries of the content-type to be managed as draft versions, before they are published (see Draft & Publish).
   Internationalization	Tick 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

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 base 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.

• Click on the Add new/another field button 1 in the top right corner to add more fields to your content-type.

• In the table that displays the fields of your content-type 2, click on the and/or buttons to respectively edit and/or delete these fields.

• Click on the Edit button 3 to access the basic and advanced settings of your content-type:

  Basic settings

  The Basic Settings tab allows to edit the following properties of the content-type or component:

  

  • 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.

  Advanced settings

  The Advanced Settings tab allows to edit the following properties of the content-type or component:

  

  • Draft & Publish: Enable the Draft & Publish feature for the content-type or component. It is disabled by default.
  • Internationalization: Enable the Internationalization feature for the content-type or component. It is disabled by default.

• Click on the Save button 4 to confirm any ongoing modification.

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.

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.

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.
