Roles
Toolbar configuration
Move a button into the Active toolbar to enable it, or into the list of Available buttons to disable it. Buttons may be moved with the mouse or keyboard arrow keys.

The toolbar buttons that don't fit the user's browser window width will be grouped in a dropdown. If multiple toolbar rows are preferred, those can be configured by adding an explicit wrapping breakpoint wherever you want to start a new row.

Headings
Enabled Headings
These are the headings that will appear in the headings dropdown. If a heading is not chosen here, it does not necessarily mean the corresponding tag is disallowed in the text format.
Media
Ensures that the latest versions of images uploaded via a Text Editor are displayed, along with their dimensions.
Uses a data-align attribute on <img> tags to align images.
Uses a data-caption attribute on <img> tags to caption images.
Disallows usage of <img> tag sources that are not hosted on this site by replacing them with a placeholder image.
Instruct browsers to lazy load images if dimensions are specified. Use in conjunction with and place after the 'Track images uploaded via a Text Editor' filter that adds image dimensions required for lazy loading. Results can be overridden by <img loading="eager">.
Embeds media items using a custom tag, <drupal-media>. If used in conjunction with the 'Align/Caption' filters, make sure this filter is configured to run after them.

Embed media
Limit allowed HTML tags and correct faulty HTML (Enabled)
With CKEditor 5 this is a read-only field. The allowed HTML tags and attributes are determined by the CKEditor 5 configuration. Manually removing tags would break enabled functionality, and any manually added tags would be removed by CKEditor 5 on render.
Convert URLs into links (Disabled)
characters
URLs longer than this number of characters will be truncated to prevent long strings that break formatting. The link itself will be retained; just the text portion of the link will be truncated.
Embed media (Enabled)
The view mode that an embedded media item should be displayed in by default. This can be overridden using the data-view-mode attribute.
Media types selectable in the Media Library
If none are selected, all will be allowed.
View modes selectable in the 'Edit media' dialog
If two or more view modes are selected, users will be able to update the view mode that an embedded media item should be displayed in after it has been embedded. If less than two view modes are selected, media will be embedded using the default view mode and no view mode options will appear after a media item has been embedded.
