Can't find how to edit CSS menu in Dreamweaver CC
After inserting a CSS menu in Dreamweaver, the size of the menu is too much and I need to bring it down so it will fit correctly. But, I can't find how to edit the menu in CC. I've enabled Invisible Elements and in Preferences, I've enabled script elements but nothing's showing up. How can I do this?
And also, a little side from this. My webpage is 961px wide, and my menu is only 320px yet it's large enough that it squeezes down onto two rows. What's the difference here?
