Navigation sub-menu is stuck (static)

For your sub-nav, you need to add this to your child theme css:

#access ul ul {
display:none;
}

Thank you I did that and it did remove the sub-nav that was stuck. However, now the sub-nav does not pop up at all. I want it to pop up when I move the cursor over “Material”

I think what you should do is grab the entire code for the menu and the sub-menu from Twentyeleven, put it into your child theme and then make the changes to it.

I don’t know what I did. But I am not using the child and now my menu is somewhat in the center and my sub-nav is working properly. do you know how I can better center the navigation? It’s off to the left.
