In a UI, I get the user to make a selection from a combo box. This selection influences what other controls will need to be shown. There are also other controls that need to be shown, independently of which item is selected in the combo box. How can I make it clear that some controls "belong" to a particular item in the combo box?
I thought of using a group box combined with a combo box, like so:
However, I believe this is not considered to be good practice, judging from the lack of such a control in the Qt Toolbox, and from the statement on the Microsoft Dev Center that one shouldn't put controls in group box labels. On that page, they recommend to use tabs instead:
But, again, this doesn't seem to be the right approach: In my understanding, tabs should be used to switch between different independent views, and not to make a selection. Will it be clear enough to users that selecting one of the tabs also makes the choice of whether "Method A" or "Method B" will be used? Is there a different commonly used approach to this problem that I've missed?
