If you mouse your cursor over the most right (black) button you see “contact” fading in, thats oke, and when you click on it a big orange shape slides in, some text is needed to put in here.

But!

When you move the mouse of the button the orange shape slides back.

So my question is, how can I make the orange shape stay while the mouse is of the button? And when the mouse moves out of the contact button and over another it should fade in that name to, (like it does now).

I hope i make my self clear and that you guys and girls have some good advice for me.
