Addressing responsiveness on AEM Adaptive forms

When we design adaptive forms with 3 or 4 columns, we noticed they tend to overlap when we switch to mobile renditions, i was under impression in the layout mode, i can arrange them, so they stack up one over the other but i noticed it stays the same after reverting to desktop rendition. Am i missing anything ?

Eventually we will be delivering this form in headless but layout is something thats under AEM scope.
