Section Collapse within a Section Collapse

Is it possible to have multiple Section Collapses within a Section Collapse itself? When taking a look at my form, I would like there to be the different 'Session Dates' in individual Section Collapse's within each of my main Section Collapses labeled "Parent/Tot" "Little Kids" "Big Kids" and "Private Lessons."

I have already read through the "Help" section on this topic, but it doesn't seem to cover Collapses within Collapses. Thank you for your help.

Unfortunately, it is not possible to insert a Section Collapse inside a Section Collapse. I suggest you use the Show and Hide Field condition. In this way, multiple Section Collapse will appear only if the condition is met.

Please refer to these guides:

Hope that helps. Thank you.
