This is what i did for mine, i hope this would help you.

Code:

<label class="desc">Select Category:</label>
<select class="field select small" name="edit_parent">
    <option></option>
    &lt;?php foreach($categories as $cat):?&gt;
    <option value="&lt;?=$cat['id'];?&gt;"&lt;?php if($cat['id'] == $editinfo['parent_id'])
    {
        echo set_select('edit_parent',$cat['id'],TRUE);
    }
    else
    {
        echo set_select('edit_parent',$cat['id']);
    }
    ?&gt;>&lt;?=$cat['title'];?&gt;</option>
    &lt;?php endforeach;?&gt;
</select>
