jQuery plugin for a simple input box for comma-separated tags with autosuggest

I'm searching for a jQuery plugin with following functionality:

1. It should display an input box, in which tags would be put in like so: 'bees, beads, beards'.
2. When a user is typing a tag, it should display an autosuggest box for the user's input.
3. The display should be plain and simple: just plain-text comma-separated tags.
4. It should allow tags containing spacebar (e.g. 'funny cats').
5. Comma symbol should be used for separation, not keystroke for ',', because some non-English keyboard layouts have commas assigned to other keys.

Is there such a plugin and if so, where can I find it?

There is Chosen, which pretty much does everything you want.

Check out the "Multiple Select" feature on their site.

This version of Chosen is not currently under active development while we decide on its future direction.
