Problem
Show long options when hovering over a fixed width selection box.
Names are hidden here:

Highlighted HTML in the browser
<select id="prim" size="5" multiple="multiple" scroabble="1" name="prim[]"> <option value="Applied Research Associates Inc.">Applied Research Associates Inc.</option> </select>
Required conclusion
Show span or title as below

Expected HTML
<select id="prim" size="5" multiple="multiple" scroabble="1" name="prim[]"> <option value="Applied Research Associates Inc." title="Applied Research Associates Inc.">Applied Research Associates Inc.</option> </select>
My CakePHP Code
echo $form->input('prim', array('options'=>$refined_list, 'type'=>'select', 'scrollable'=>true, 'multiple'=>true, 'name'=>'prim', 'label'=>false, 'size'=>'5'));
What attribute should be added to make the desired changes?
EDIT / UPDATE: One way might be to update the $refined_list with the title field, as suggested by @ammu. I have to wait for a better solution.
