Edit Drop Down Menu

My drop down menus are not spaced properly. I want:
The words on one line (not two lines)
I want an arrow beside the menu items to indicate there is a submenu
I want the menu and the submenu to be flush – currently, there is a lot of space between them. Example: Product Reviews & Faves/ Subscription Services / Birchbox. There is a lot of space between Subscription Services and Birchbox.
