DoNotHide FOCUS GROUP Option

What would the likeliness of a do-not-hide state for the focusgroups be? I have many situations were focus within focus (sub menus of a drop menu) when used with repeating groups, and the first level vanishes when interacting with the next group. I have to make all these rules to try and keep things working right, and they cause all kinds of issues like resetting forms and inputs.

I would like to say something like if this url pram = menu=true OR if this menu is visible, NEVER hide this focus group.

I found it much easier to build the menus with normal groups that collapse height when hidden. You also get a nice smooth slide up / down feature when you open / close menu and sub menu items
