Hi, I have the following issue,

I need to use jquery ui autocomplete in a textarea in lightning. In a visualforce page works perfectly, but in a lightning component it does not work, the list of suggestions does not appear.

In the browser console there is no error, and if through a console.log I print what has the source attribute shows me the whole list, ie the list loads well but there is a problem that does not want to show suggestions to the typing time.

jquery ui 1.12.1
jquery 2.2.4

also try with jquery 1.11.4 and it does not work either.

Any ideas?
