Anyone who interested for this feature, you should look Active Tags first. This project will no longer update by me since the main feature can be replace by other modules.
If anyone are interested for taking this project, feel free to contact me.
This module is an enhance for free-tag input field.
Tag is free, but one major problem of autocomplete input style is that we don't have enough guide for customer. Sometimes we need to let user "choose" exists tag by simple click, and of course they still can add their own defined tag in textfield.
See picture then you know what this module does.
