Question concerning Submenu und Posts

Hi, I have two questions, but don't wanna start two different topics: 1. I have this site and i want to open it with my Samsung-Tablet When I try to reach the submenu "History" I have always to touch the Main-Menu "About me" - only when I touched it, the sub-menus roll out (I hope you understand, what I mean ;) ) And then was sent to the Page for "About me" --> How can I disable that I'm sent to the site of the main-menu "About me" and just touch this part of the menu, to roll the sub-menus out? 2. I have a Pic in my slider as feautered content - so it shows up in the Slider. But I don't want the Posts for this not on my first site. How do I do that?
