Spry menu, change the width

Hi.

I'm working with spry drop down menus in dreamweaver. (horizontal)

I was wondering, if there's any way you can go change the width on the menubokses so each one of them have different sizes?
I've tried out, but it won't work for me.
Should/can i go make more spry menus?

I've made my design in photoshop, and i can't make drop down menus out from the menu pictures i've made, så I have to do a spry menu and some howput the pictures in. (i've sent a picture of my design with the Question)

What to do.

Please help!
