Form like Wordpress Tags Box

Hello,
I am creating a backend for an app and was wondering if anyone knew of a script or applet that I can utlize that is like the Wordpress TAGS box.
Basically, in my backend, admin will create tags for a specific item, but I want the ability to start typing, it will query database for similar tags. If not found, insert and make it easy to delete

Hi xeonman,

For autocompleting tags you’ll need to use javascript, so it might be worth reposting in that forum rather than the php one. As a pointer in the right direction though, you might want to checkout the jquery UI autocomplete widget - that should get you halfway to what you want.
