Lost Category Search Option

At some point while adding categories, the category search drop down went away (on home page). Now there’s just the standard search field and no drop down box for searches within a selected category. Does this feature disable itself after you reach a certain number of categories or subcategories? Anyway to bring it back?

Also, is there a way to turn off the pop out menus on the home page navigation. I hear that this feature slows down the page loads and I would like to disable it.

Thank you in advance for the help. :slight_smile:
