Pass Array of Parameters to XMP Template

<p>By chance would it be possible to pass multiple values to an XMP Template?</p><p>I am trying to implement multiple drop down filters to a site. Here is the example of what I am trying to do&nbsp;<a href="http://aerosd.org/entries/directory">http://aerosd.org/entries/directory</a></p><p>And here is my attempt so far</p><p><a href="http://steamtest.sdcoe.net/directory">http://steamtest.sdcoe.net/directory</a></p><p>However the more template I add, the more paging it is adding. So I was wondering if I can just create static HTML dropdown list and add a button. When that button is clicked then I collect the values and pass to the XMP template in the same page via location.href</p><p>I am open to pointers to any other approach that achieve the desired multi dropdownlist filter.</p>
