In your screen, you have a collection based on your table A.
In the “Actions” tab associated with the collection, go to the “Collection item workflows” section.
Add an “Update” action → “Show edit screen” (Data: This item, Target: Overlay).
Add a “Delete” action → “Show new screen” (Data: This item, Target: Slide in).
Now, let’s set up the “Slide in”…
Add text asking to confirm the deletion.
Add a “No” button → Action: “Close overlay”.
Add a “Yes” button → Action: “Delete row”, Rows: This item.
or add a button block with same actions.
Enjoy!
That’s all
