Display suggestions

Suggestions are used to display the changes that the AI Agent has made to the document. Each suggestion contains the following data:

  • The range of the document that has changed
  • The new content that should be inserted at that range. This content can be in different formats, like HTML, JSON, or plain text. There can also be multiple replacement options for the same range, and the user can choose which one to use.

The Suggestion object

A Suggestion represents a proposed change to a range of content in the editor, typically generated by an AI agent. It allows previewing, reviewing, and applying changes, and can include multiple replacement options.

Properties

  • id (string): A unique identifier for the suggestion.
  • range (Range): The range of content in the editor that the suggestion applies to.
  • replacementOptions (ReplacementOption[]): One or more possible replacements for the selected range. The user can choose which option to apply. Each ReplacementOption can be one of the following types:
    • SliceReplacementOption (type: 'slice'):
      • id (string): Unique identifier for this replacement option.
      • type ('slice'): Indicates this is a slice replacement.
      • addSlice (Slice): The ProseMirror Slice object to insert as the replacement content.
      • metadata? (any): Optional extra metadata for this replacement option (e.g., source, category).
    • TextReplacementOption (type: 'text'):
      • id (string): Unique identifier for this replacement option.
      • type ('text'): Indicates this is a text replacement.
      • addText (string): The plain text to insert as the replacement content.
      • metadata? (any): Optional extra metadata for this replacement option (e.g., source, category).
  • metadata? (any): Optional extra metadata for the suggestion. This can be used to store additional information such as the source, category, or any custom data. It is not used internally by the extension but can help customize UI rendering.
  • displayOptions? (DisplayOptions): Optional display options to control how the suggestion is rendered in the editor UI.
    • showAsDiff? (boolean): Show alternative content as a diff widget. Default: true.
    • diffPosition? ('before' | 'after'): Where to display the diff relative to the suggestion. Default: 'before'
    • attributes? (Record<string, any>): Attributes added to rendered elements
    • renderDecorations? (RenderDecorations<{ suggestion: Suggestion }>): Custom rendering function. Defaults to a function renders the suggestion as a diff.

Parameters

  • inputs (SuggestionsFormat[]): A list of suggestions in one of the following formats:

Styling suggestions

When the default renderDecorations function is used, the following classes are applied:

  • .tiptap-ai-suggestion: Applied on the content that is covered by the suggestion range.
  • .tiptap-ai-suggestion--selected: Applied when the cursor is inside the suggestion range.
  • .tiptap-ai-suggestion-diff: Applied on the diff widget that is displayed next to the suggestion range.
  • .tiptap-ai-suggestion-diff--selected: Applied to the diff widget when the cursor is inside the suggestion range.

Use the above classes to style the suggestions, or provide a custom renderDecorations function for full control over the UI.
