Multiple choice labels in forms

Hello everyone.

I would like to create a form in which i can choose from a long list of keywords and select the relevant ones that will then row next to each other like in this form.
Does anyone have an idea how to achieve this?

Thank you!


Custom code,

Check out this jQuery plug-in:

Thank you Sam! That’s helpful. However I would like users to use only predefined keywords that they can select from a dropdown and which are then added as a “label” (see screenshot). Any idea how to accomplish that?
