Hi!

Hello, I'm using the theme "Press". I want td delay secondary menu. I know how i can make it.But how can I do that would be in the main menu displays the name of the page rather than the names of columns? How can I do that would button "Home" does not display the main menu? Tell your reply to my mail, please. **********@*****.com Thank You!

By default, there are two menus always visible on your screen, the "Main" menu and the "Top" menu. To customize any of them you have to go to the page Appearance => Menus and set the created menu as a main/top menu. Here are the intelligible instructions:
