If you simply put the above code into the left column of the table it should work how you want with regards to the right column.
As for the drop down box you'd need to add the drop down to the same form which handles the search:
Code:
<select name="category">
<option value="" selected="selected"></option>
<option value="sport">Sport</option>
</select>
Then change:
Code:
$field_to_search3 = "category";
To:
Code:
if(isset($_GET['category'])){
$field_to_search3 = $_GET['category'];
}else{
$field_to_search3 = What_if_category_not_searched?
}
This should work
