I recently hit the exact same issue. It's a useful widget but has no demos (see https://phabricator.wikimedia.org/T85467) Luckily after a week of fiddling Florian and I have two demos that are working. The code in the following patches should help you work out. I understand that Andrew Garret is setting up a demo site. I wonder if during the dev summit we could get s demo for this done and on it? https://gerrit.wikimedia.org/r/181225 https://gerrit.wikimedia.org/r/180880 On 10 Jan 2015 04:37, "Ricordisamoa" &lt;ricordisamoa(a)openmailbox.org&gt; wrote: Thanks. I eventually managed to use ProcessDialog and several widgets in a script of mine <https://it.wikipedia.org/wiki/Utente:Ricordisamoa/PDC.js>. I just couldn't make LookupInputWidget work (phab:T85467 < https://phabricator.wikimedia.org/T85467>gt;, mw:Talk:OOjs UI#OO.ui.LookupInputWidget vs jQuery autocomplete < https://www.mediawiki.org/wiki/Talk:OOjs_UI#OO.ui. LookupInputWidget_vs_jQuery_autocomplete>), and had to fall back to jQuery UI's autocomplete. The 'solution' I've come up with is, more or less: var widget= new OO.ui.TextInputWidget(); widget .$input .autocomplete( { source: function ( request, response) { response( [ request.term + 'test 1', request.term + 'test 2', request.term + 'test 3' ] ); } } ); Very few examples can be found of LookupInputWidget. Does anyone have any hints about it? Il 19/10/2014 17:49, Bartosz Dziewoński ha scritto: OOUI is reasonably stable and can be used in gadgets, if you wish to.
