Currently there is no component for adding text to an input from some datasource. There is an autocomplete but it does not allow mixing freetext and text coming from a datasource. And it only allows for one value.

What we need is exactly this  :  http://jeff-collins.github.io/ment.io/#/

Typing a special character in a textbox (#, or @) would bring a datalist the user can choose from.

Can this be implemented please  ?
