You either want to use the Edit screen for that item (action → show edit screen) or build a “custom form” where the form updates an item (set column value).
I’m just dropping this here so I have something to refer people to when they ask.
This is a simple concept app (copyable), that demonstrates the following techniques:
Building custom forms for adding and editing list items (as an alternative to the native forms provided by Glide)
Preventing duplicate new entries using User Specific Columns and Relations
Enforcing mandatory input items
The use of visibility conditions and user specific booleans to control user flow
There is nothing particula…
