Dropdown Menu for Query_Posts

Here’s a simple example of a PHP dropdown, hope this helps.

<select name="mydropdownlist">
<?php
    $options = array('option1' => 'option 1'
                 'option2' => 'option 2'
                 'option3' => 'option 3');

    foreach($options as $value => $caption)
   {
        echo "<option value=\"$value\">$caption</option>";
   }
?>
</select>
