Unable to drag and drop adaptive form in AEM form container in classic ui

Hi,

For dragging adaptive form on page, first I added AEM form container in parsys, but after that I am unable to drag and drop adaptive form to this form container in calssic ui, also I am not getting edit option for this container.  Whereas if I switch mode to touch ui, there I am able to do so, please suggest is there any thing extra I need to do for classic ui or is classic ui do nots adaptive forms.

Thanks,
