U8glib menu help

Hello !
I am making a watch and I need a menu, what I found is only 1/2 of what I need.

My menu items are:
- Clock
- Stopwatch
- BMP180
- Flashlight
I want when I press the button select to open the page of the sunction also each func to work separately from the others.
So can somebody explain show me how to make it ?
