Subpages Won’t Show in Dropdown

I have changed the depth higher, but it places the subpage right under the current link instead of putting it in a drop down, and the subpage is non-clickable. If that makes sense.

<?php wp_list_pages(‘sort_column=menu_order&depth=3&title_li=’);?>

Sorry. I had to turn it off, otherwise it stretches the template. They are turned on now.

Thank you.
I’ve tried both CSS and JavaScript and the same problem occurs. Any other recommendations?
