Sub Menu does not ‘stick’ when hovering

Hi,

2 things:

1. When you hover over a Menu option,it should show a drag down option of a sub menu with links to other pages. When i hover on my menu item, it shows the sub menu but it does not stick.

2. because of point 1, when i view the page on mobile view, when clicking Menu, it automatically drags the users screen to the middle of the screen.
