autocomplete tags in textarea? I need a tagging functionality for my content type. The normal term reference tag autocomplete widget has a problem, because I can't find a way to use textarea instead of textfield for it. I would need textarea to be able to see all tags while typing them. One node will have 10-20 tags, some of which are not just words, but expressions. So it all takes place and textfield is not acceptable.

How to enable entering tags into textarea with autocomplete?

Autocomplete Delux:

This is an enhanced autocomplete element, that uses the JQuery UI autocomplete. It will also implement a widget for taxonomy.
