Allowing users to add, edit & delete records can be very powerful, but sometimes you want to restrict this to only certain items or to certain users. With conditional add, edit & delete you can do this.
If you only want certain items to be editable, you can set up a condition that achieves this. For example, in the GIF below we make only one of our items editable - by adding a condition of
Name = Marie Rao. This results in only that item being editable.
We've entered a Custom Value here, which only matches one item. This is a very simple example. However, you could instead choose a Column Value and make the condition dynamic for each row. To do this, we can just select the three-dots menu and select one of the columns.
You can also set conditions for deleting items, the same way you set conditions for editing items.
You might also want only to give edit access to items that 'belong' to the signed-in user.
In the GIF below we enable editing on our list items. After that, we add a condition where the item is only editable if the signed-in user's email matches the email column in our table.
This means that Marie Rao (who we have signed in as) is able to edit her record, but not any of the others.
Using user profiles, you can enable only people with a certain 'Role' to be able to add items. You can add this condition on the 'Add' panel of a list screen's configuration
