title: Post to current page, keeping querystring values in tact
body: <p>I have a page that I want to create a drop down list, and post back to the same page that I am on now.</p>
  
  <p>How can I do this?</p>
  
  <p>One catch is, I want all the querystring values to be the same also, except for 1 which is what the drop down list will be overriding.</p>
