Here is the structure of my data:
Here is how the first step of the wizard would look like.
Here is how they can skip to any further step in the wizard by either selecting a different group or sub group:
Now my problem is how do I show that drop list to select when the user is on a step other than the first one. (I don't want these titles [Group and Subgroup] to be as simple dropdowns controls). When the user is on the first group, I can show the list in order. But on the second group, it boils down to something like this, which I think has to have a better way of displaying.
