The Term Reference field type has three stock widget types:
- Select List
- Check boxes/radio buttons
- Autocomplete term widget (tagging)
We need an alternative to the autocomplete widget that shows all existing terms in a vocabulary and allows users to enter another.
Here is a sample of what I'm looking for (I just made this in Firebug—I don't have a viable option yet). In this option, the vocabulary would include two terms, banana and pear, and the user could enter a different term.
