Menu items too long – submenu not working?

Hi,

I am building a site for a client who designs greetings cards, and the dropdown menu items for her Occasions range of cards is pretty long. I find when I hover over it that the screen doesn’t display the last few menu items, and my mouse/trackpad won’t scroll down.

I thought I could move some into the submenu positions (by dragging and dropping in the menu so that they are indented under parent menu items) – but that does not seem to have made a difference to the way the menu items display on the frontend??

Can you advise on whether I have some settings wrong and a scrolling option is not configured, or whether I need to reduce the menu items, and if so, how can I nest them under parent items?
