Forms with Sub-forms

In my Trip Planner app I have 3 child tables (Transport, Accommodation and Activities) linked to a parent Cost table. Ideally I need a sub-form (Cost) in a main form (eg Accommodation) for optimised user experience. Some forms platforms have the sub-forms option available eg Airtable, Fillout… Is this a possibility in Softr?

Eg When I create a new Accommodation record, I need a linked Cost record created. Is there a way to create a sub-form to create the Cost record from the Add Accommodation record form?

My current approach is to (eg Accommodation)

  1. Click the Add Accommodation Item button
  2. Enter the relevant data then Click the Add button at the bottom of the form
  3. Hit the Cost link in the Navigation panel on the left of the form
  4. Click on Add Cost Item and enter the relevant data
  5. In the Accommodation field search for and select your Accommodation activity that you just created
  6. After completing the relevant data fields click Add at the bottom of the form
  7. Click the Costs button at the top of the page to confirm your item is in your Trip Wallet along with the cost, payment, booking and other details
