Nav bar drop down menu

Hi, I am a newbie and just cant seem to figure out this problem. I created a site and used a navigation bar just adding it from the add panel. When I view it on ipad or phone the drop down menu appears in a horizontal flow directly under the nav bar. However when moved to a phone its scrunched and appears jumbled. How do I make the list stack on the left side in a vertical column. I’ve tried settings for the container, the link, the bar, nothing seems to affect it. Could someone help me? (this is only in the open state. )
