How to dissapear the buttons when one button is

Hello, i explain.

On http://busimatch.com, i want when people click on Busimatch store, alle other buttons are away.
But i want that when the Busimatch button is clicked, other buttons are there.
is it possible? Of course when people click on the logo, the original menu is there again.
I it also possible when peolple click on your niche, the people comes to the selected niche and that all buttons are away.
I ask this to symplify the structure of Busimatch so people always can click on the logo above so see the original menu.
When preople click on a menubutton, other buttons come there in the place.

Yes, using javascript code.
