Quill Mention

Quill Mention is a module to provide @mentions or #hashtag functionality for the Quill rich text editor.

Demo

Getting Started

Install

Install with npm:

npm install quill-mention --save

Install with Yarn:

yarn add quill-mention

Import package

import "quill-mention";
// or
require("quill-mention");

Importing quill-mention automagically adds it to Quill modules.

Now you only need to pass quill-mention config to quill.

Example

import "quill-mention";

const atValues = [
  { id: 1, value: "Fredrik Sundqvist" },
  { id: 2, value: "Patrik Sjölin" }
];
const hashValues = [
  { id: 3, value: "Fredrik Sundqvist 2" },
  { id: 4, value: "Patrik Sjölin 2" }
];
const quill = new Quill("#editor", {
  modules: {
    mention: {
      allowedChars: /^[A-Za-z\sÅÄÖåäö]*$/,
      mentionDenotationChars: ["@", "#"],
      source: function(searchTerm, renderList, mentionChar) {
        let values;

        if (mentionChar === "@") {
          values = atValues;
        } else {
          values = hashValues;
        }

        if (searchTerm.length === 0) {
          renderList(values, searchTerm);
        } else {
          const matches = [];
          for (let i = 0; i < values.length; i++)
            if (
              ~values[i].value.toLowerCase().indexOf(searchTerm.toLowerCase())
            )
              matches.push(values[i]);
          renderList(matches, searchTerm);
        }
      }
    }
  }
});

Async example

async function suggestPeople(searchTerm) {
  const allPeople = [
    {
      id: 1,
      value: "Fredrik Sundqvist"
    },
    {
      id: 2,
      value: "Patrik Sjölin"
    }
  ];
  return allPeople.filter(person => person.value.includes(searchTerm));
}

const quill = new Quill("#editor", {
  modules: {
    mention: {
      allowedChars: /^[A-Za-z\sÅÄÖåäö]*$/,
      mentionDenotationChars: ["@", "#"],
      source: async function(searchTerm, renderList) {
        const matchedPeople = await suggestPeople(searchTerm);
        renderList(matchedPeople);
      }
    }
  }
});

Note: if you whitelist quill formats via "formats" option, you need to add "mention" format there. Another way quill-mention won't work. Here's an example with whitelisted formats:

const quill = new Quill("#editor", {
  formats: ["bold", "italic", "mention"],
  // note "mention" format above
  modules: {
    mention: {
      allowedChars: /^[A-Za-z\sÅÄÖåäö]*$/,
      mentionDenotationChars: ["@", "#"],
      source: function(searchTerm, renderList, mentionChar) {
        // some source implementation
      }
    }
  }
});

Settings

Property	Default	Description
source(searchTerm, renderList, mentionChar)	null	Required callback function to handle the search term and connect it to a data source for matches. The data source can be a local source or an AJAX request. The callback should call renderList(matches, searchTerm); with matches of JSON Objects in an array to show the result for the user. The JSON Objects should have id and value but can also have other values to be used in renderItem for custom display.
renderItem(item, searchTerm)	function	A function that gives you control over how matches from source are displayed. You can use this function to highlight the search term or change the design with custom HTML.
allowedChars	[a-zA-Z0-9_]	Allowed characters in search term triggering a search request using regular expressions
minChars	0	Minimum number of characters after the @ symbol triggering a search request
maxChars	31	Maximum number of characters after the @ symbol triggering a search request
offsetTop	2	Additional top offset of the mention container position
offsetLeft	0	Additional left offset of the mention container position
mentionDenotationChars	["@"]	Specifies which characters will cause the mention autocomplete to open
isolateCharacter	false	Whether or not the denotation character(s) should be isolated. For example, to avoid mentioning in an email.
fixMentionsToQuill	false	When set to true, the mentions menu will be rendered above or below the quill container. Otherwise, the mentions menu will track the denotation character(s);
showDenotationChar	true	Whether to show the used denotation character in the mention item or not
defaultMenuOrientation	'bottom'	Options are 'bottom' and 'top'. Determines what the default orientation of the menu will be. Quill-mention will attempt to render the menu either above or below the editor. If 'top' is provided as a value, and there is not enough space above the editor, the menu will be rendered below. Vice versa, if there is not enough space below the editor, and 'bottom' is provided as a value (or no value is provided at all), the menu will be rendered above the editor.
dataAttributes	['id', 'value', 'denotationChar', 'link', 'target']	A list of data values you wish to be passed from your list data to the html node. (id, value, denotationChar, link, target are included by default).
onOpen	function	Callback when mention dropdown is open.
onClose	function	Callback when mention dropdown is closed.
onSelect(item, insertItem)	function	Callback for a selected item. When overriding this method, insertItem should be used to insert item to the editor. This makes async requests possible.
linkTarget	'_blank'	Link target for mentions with a link
listItemClass	'ql-mention-list-item'	Style class to be used for list items (may be null)
mentionContainerClass	'ql-mention-list-container'	Style class to be used for the mention list container (may be null)
mentionListClass	'ql-mention-list'	Style class to be used for the mention list (may be null)
spaceAfterInsert	true	Whether or not insert 1 space after mention block in text

Styling

To allow styling based on the menu orientation, a class is added depending on the orientation and the mentionContainerClass option. By default this will be ql-mention-list-container-bottom or ql-mention-list-container-top.
