How to create Sub Select Option on Main Option Selected in Airtable form

[ravenkao]

I have four selections available in a picklist. Each selection has a different set of options associated with it. I want to create a secondary list of options that users can select from that changes depending on their primary selection. For example they choose from:Selection A
Selection B
Selection CIf they choose Selection A, a secondary option box appears offering
Option 1
Option 2If they choose Selection B, a secondary option box appears offering
Option 3
Option 4..and so on. How do I construct this?

This has been my number one Feature Request for Airtable to develop for the past six years now.

The behaviour that you’re after can only be done either in a scripting App, where users would need to have an AT account and access to the Scripting App extension - or you’ll need a 3rd party Form app that has this feature. 

I really don’t understand why AT hasn’t developed this one feature yet. It’s disappointing to say the least.

To clarify, that there are field dependant visibility options in a View Form, but you can’t hide/show select data to choose from within the shown fields themselves- in that, a fields selectable data is either all or none.

you can create single select elements as follows :
"A - Option A.1"
"A - Option A.2"
"A - Option A.3"
"B - Option B.1"
"B - Option B.2"
"C ..."

So that, when you type A in the single select searchbar you only see, the sub section option of A.
