Where to find it
When a form’s mode is set to Edits records, the form editor’s Build list shows a Record picker section. This is where you decide which records people can choose to edit.
The settings
Records from
Choose Whole table or a specific Airtable view. The default is the whole table. A view brings its own filter and sort, so the picker follows what that view already shows. (Free.)
Second line
Choose which field appears as the second line under each record, so people can tell similarly-named records apart. The default, Automatic, picks the first meaningful field. (Free.)
Filter records
Add a condition to narrow the pickable records further. It applies on top of any chosen view. (A Pro feature.)
The scope is a starting point
What you set here is where the picker opens. The person editing can still switch the view, and the sort, while they choose.
At fill time the picker is titled Choose a record and includes a Search records box. When a view is active, it shows From view: [name].
