The structure looks like this:

  • Popup
    • Group User
      • Edit icon
      • Group containing User info - visible by default
      • Group input form to change User - hidden by default
    • RG Children (with custom state)
      • Group Child
        • Edit icon
        • Group containing Child info - visible by default
        • Group input form to change Child - hidden by default
    • Group buttons - hidden until an edit icon is clicked
      • Cancel button
      • Save button

Unfortunately, I’m not able to find any of the inputs in the Child’s input form in the expression of the workflow action. I suspect it is because Bubble views this as a risk and is disabling it (because imagine executing a workflow that is based on one input in a repeating group list of 20 items simultaneously), but from a UI perspective it’s a pain to work around.
