Just add data-role="tagsinput" to your input field to automatically change it to a tags input field.
data-role="tagsinput"
Use a <select multiple /> as your input element for a tags input, to gain true multivalue 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.
<select multiple />
<option />
