Stack Overflow Question Tag Textbox
<p>I'm looking to implement something similar to the Tags textbox on Stack Overflow.</p>

<p>Ideally, the tag suggestions will come directly from the database or else be loaded straight from the database and multiples can be selected. I'd like to be able to insert values to the database if they're not contained in the dataset.</p>

<p>Anyone have any good implementations of this that I can refer to?</p>
