Returns

The control can return any of or all of the following output types, and will accept any as an input.

Text

For when only the text matters, will operate as a normal control, returning text when the control is blurred.

Object

Object return

IEditorV3

{
  lines: [{
    textBlocks: [{
      text: string,
      style?: string,
      type?: "text" | "at",
      isLocked?: true | undefined,
      lineStartPosition?: number,
      atData?: Record<string, string>,
      maxAtListLength?: number,
    }],
    contentProps?: EditorV3ContentPropsInput
  }];
  contentProps?: EditorV3ContentPropsInput,
}

The values for contentProps will always be the same for all entries in the object, but are copied for convenience

AtListFunction

Assigning a function to this parameter will enable collaberative @mentions.

EditorV3ContentPropsInput

This is mainly for internal use, and will be over ridden by any settings in the editor, however given here for completeness

{
  allowMarkdown?: boolean,
  allowNewLine?: boolean,
  decimalAlignPercent?: number,
  markdownSettings?: IMarkdownSettings,
  showMarkdown?: boolean,
  styles?: EditorV3Styles,
  textAlignment?: EditorV3Align,
  atListFunction?: (typedString: string) => Promise<EditorV3AtListItem<Record<string, string>>[]>,
}

The value of style in any given text block, should match one of the keys in the style object, the CSS styles from the object will then be applied to the text block.

EditorV3Style extends React.CSSProperties {
  isLocked?: boolean;
}
EditorV3Styles {
  [styleName: string]: EditorV3Style;
}

isLocked has been added as a style property, to allow blocks to be non-editable. They still can be deleted in their entirety. This is used for @mention blocks.

Editor utility

Cut and paste

Styles pasted between different controls will be kept, other objects pasted into the control will be pasted as plain text.
