You have quite a grouping there.

You have Group B inside of Group G inside of Group Name inside of Group Tell Us About Yourself inside of Group Welcome inside of Group H inside of Group User.

I think I would try and better organize your data.

Anyway, your Group B responsiveness is going to be dependent on its parent groups and on up the line.

I see your Group B (which is a row) has 2 groups in it with no minimum. That means anything in Group B will shrink to Group B’s minimum…which will shrink to its parent elements minimum etc., and the groups in it won’t go into a column format.

You need to set a minimum on a group when you have it in a row if it has other groups in that row if you want it to go into a column format.

The maximum you set will either depend on the parent container or your set max.

I would suggest you look all the parent containers Group B is in and start from there and then look at each child element in descending order and fix the responsiveness of each one.

A lot of times (usually) when you have a responsive issue, there’s a good chance it will be because of a parent element.
