Question: I'm searching an userpicker that looks like Gmail, that when you add a "To" address, it becomes a label, or like StackOverflow when you add tags

I've found this plugin:
 <http://htmlpreview.github.com/?https://github.com/ErikNoren/entitypicker/blob/master/entitypickerdemo.html> 
but I would like to find more plugins to compare...

In my case, In my case, I need to convert two values (mail and phone) in one label...How can I do it??

Thank you very much!

Answer: 
My current autocomplete plugin of choice is Select2.

You can find it here
<http://ivaynberg.github.io/select2/>
Things have gotten easier with plugins Nowadays.

Checkout the <https://github.com/jshjohnson/Choices>

The plugin works with `text input`, `select` and `multiple select`

With this JS plugin, you can even validate items before you add to a list.

```
For example:

 1. You can write your own validation rules
 2. You can use Regex among other awesome things

```

Its quite easier to initialize:

```
var choice = new Choices(document.getElementById('itemID'), {
  option1:option, 
  option2: option
}

```

It even has several callBacks like; `removingItems`, `addingItems` etc

Example Implementation:
