Tags Input
Bootstrap Tags Input
Add class of.form-control with
<input> tag
data-role="tagsinput" to your input field
to automatically change it to a tags input field.
<select multiple /> as your input
element for a tags input, to gain true multi value support. Instead
of a comma separated string, the values will be set in an array.
Existing <option />elements will automatically be
set as tags. This makes it also possible to create tags containing a
comma.
