swapping menus on a dialog

Hello,

We have a dialog box that has a very big menu. I would like to have a smaller menu when a check box on the dialog is checked.

I haven't tried this yet, just wanted to run it by you guys to see if there is a better way.

Would this work. When the check box is checked we detach the current widget and attach a new widget with the bigger or smaller menu?

All the best.

P.
