Objects as tags
Not just support for using strings! This means you can use different values
for a tag's label and value. Each tag also holds a reference to the object
by which it was created, so by calling tagsinput('items') an
array of the original items is returned.
True multi value support
Other implementations just concatenate the values to a comma separated string.
This results in val() returning just this string, and when
submitting the form, only one big, concatenated value is sent in the request.
Bootstrap Tags Input provides true multivalue support. Just use a
<select multiple /> as your input element, and
val() will return an array of the tag values. When submitting the
form, an array of values will be sent with the request.
Typeahead support
Integrates with Twitter Bootstraps's typeahead.
Angular JS directive
Include bootstrap-tagsinput-angular.js and register the 'bootstrap-tagsinput' in your Angular JS application to use the bootstrap-tagsinput directive. Look at the examples page how to use the directive.
