I am using two dropdowns in a search function for the blog. So, what I need to do is get the unique values for field x and then turn the results into a dropdown - can anyone help?

The 2 simplest options off the top of my head:

1. Post the form back and have a conditional add of the second form if the first dropdown is set. Psudocode:

// form code
if( isset($data['firstDropDown'] } (
    $fields->push( new DropDownField('secondDropDown','Second: ',array('otherdata')) );

// form post function
if( ! isset($data['firstDropDown'] ) {

2. Use jQuery or something with an Ajax Action button on the first dropdown to create/populate the second dropdown. Docs:
