Manual talk:Enabling autocomplete in a form

UI Widget class
One additional note, the input box you are trying to add search to (mw-massmessage-form-spamlist in the example) must inherit the CSS class ui-widget from some ancestor in it's DOM tree. Most areas on a wiki page do. Some do not, including the part of the Editor page level that includes the template list and its siblings. Iowajason (talk) 21:51, 24 October 2015 (UTC)
