title: How do I store extra data together with Tag-it tags?
body: <p>We are using <a href="https://github.com/aehlke/tag-it/" rel="nofollow noreferrer">Tag-it</a> with an Ajax call as a <code>tagSource</code> for tagging content. We need to include more data than the tag label itself, e.g. an id different than the label or metadata such as type of tag. Data that is returned to the Ajax call but we wouldn't like to include in the tag label itself.</p>
  
  <p>We could modify Tag-it to include data with <code>li</code> items using <a href="https://stackoverflow.com/questions/3292441/jquery-store-additional-extra-data-info-inside-a-jquery-object">jQuery's <code>.data</code> method</a> but if someone else already have solved this or can recommend another tag library it would be highly appreciated.</p>
