Flexible Editor for Directus

<!-- NOTE: [extension-description] Sync description with GitHub, custom-messages.ts and package.json -->

A rich text editor (WYSIWYG) with JSON output that allows the integration of M2A relations to make it extremely flexible.

(Demo Video)

Under the hood, it integrates the Tiptap editor as an extension to the Directus app and uses an optional many-to-any (M2A) field to place and link relation nodes in the editor. This combination makes Flexible Editor a truly rich editor.

Installation

Basic Usage

In your Directus app simply click the Create Field button and select Flexible Editor.

Usage with relation nodes

<!-- Sync heading with link above `#usage-with-relation-nodes` -->

You can insert items from your Directus collections into Flexible Editor. This is optional but gives you extreme flexibility when creating rich content. To do this, you need to add a many-to-any (M2A) field, that the editor field can connect to. For Flexible Editor to work in this way, you must create the junction collection before adding a M2A field.

(Video about usage with relation nodes)

  1. Create a new (junction) collection and give it a name like xxxx_editor_nodes and set the Type of the Primary Key to Generate UUID. Finish the setup to create the collection.

  2. Open the data model of the collection to which you want to add Flexible Editor, click Create Field in Advanced Mode, and select Many to Any Relationship.

  3. Enter a name for the field, such as editor_nodes and uncheck Auto Fill on the Relationship tab, so that you can manually select the junction collection you created earlier (such as xxxx_editor_nodes). Select the Related Collections you want to integrate into your Flexible Editor field. You don’t need to set a sort field, but you do want to set the Relational Triggers to cascade when an item is deleted or deselected.

  4. On the Field tab, set the field to Hidden on Detail because we are managing the M2A items through Flexible Editor. Therefore, no interface is required for the M2A field.

  5. Now that you have created your M2A field, open the interface settings for your Flexible Editor field and connect to the M2A field by selecting it in the M2A Reference Field.

  6. Set the Item Duplication Fields for your junction collection (xxxx_editor_nodes) in the data model settings. This is required for copy & paste or drag & drop to work.

    Tip: If you set up Flexible Editor in the same way for different collections, you can copy and paste the duplication settings via Copy Raw Value from the field menu — by clicking on the “Item Duplication Fields” label.

Things to keep in mind

You cannot use the same M2A junction collection for multiple collections (where you use Flexible Editor). This would only work with an any-to-any relationship, which Directus doesn't support at the time of writing.

You should not set Item Duplication Fields for nested Flexible Editor fields as they are managed by their own junction collections.

If you want to duplicate nested M2A items (e.g. a Related Content collection, that references several other collection items), you want to duplicate only the IDs (in the junction collection) without copying the whole item!

<!-- TODO: [Stage 2][docs] Duplication -->

Duplication currently only works within the same editor field or between Flexible Editor fields, that use the same M2A Reference Field. (This will be improved in future releases.)

This also means that you can use the same M2A Reference Field for multiple Flexible Editor fields, although this is not recommended as this will change in future releases.

The current implementation of duplicating relation nodes (M2A items) does not cover all use cases, but will be improved in future releases. If the duplication fails, you should get a warning.

Custom Editor Styles

To override the CSS of the editor content, you can add Custom CSS to your Project Settings in Directus. You can use the .flexible-editor & .flexible-editor-wrapper classes for the editor itself as well as a .relation-block class for the relation nodes.

Rendering in the front-end

To render the JSON content generated by Flexible Editor you can follow the official Tiptap guide or you can use the Flexible Editor Content tools included in this package (recommended).

Rendering with interactive components

If you want to render your JSON content with interactive components, especially when using relation nodes, follow the Flexible Editor Content guide.

Rendering plain HTML or plain text

Tiptap provides official functions to generateText() or generateHTML() from the JSON output. Note that as of this writing, there are different versions of generateHTML(): one for client-side rendering (import { generateHTML } from "@tiptap/core") and one for server-side rendering (import { generateHTML } from "@tiptap/html")!
