PhpDig.net - How do I modify the template tags output?

for instance:
<phpdig:form_dropdown/>

spits out output like:

Code:

Narrow Path to Search: 

<select name='path'>

<option value='Dir1/' selected>http://somesite.com/Dir1/</option>

<option value='Dir2/' selected>http://somesite.com/Dir2/</option>

<option value='Dir3/' selected>http://somesite.com/Dir3/</option>

<option value='Dir4/' selected>http://somesite.com/Dir4/</option>

<option value='Dir5/' selected>http://somesite.com/Dir5/</option>

</select> <a href="search.php">Restart</a>

which is not quite the look I want. where is the code that defines what the output of the form_dropdown tag should be?

I would like to be able to modify most or all of the tag so if they are in a few different places let me know.
