Need parent page to stay hover mode when highlighting children in wp_list_pages

So I have created the navigation system I need and have styled it. I am using wp_list_pages and everything is going great except for one little thing. I want to have the parent menu link (ex. About) stay in it’s hover state when I am moving my mouse over the child pages in the drop down list.

When I click on About the background turns blue and the drop down appears, when I move my mouse over any of the drop down links the About background goes back to white.

Any way of doing this? (I hope so… ??
