How to add a popup message on a list view

[Alessia Russo]

Hi everybody! I would show a popup with an alert message if a user is tring to make an action from a list view with the box of 'actions on selected row'. So after it shows this pop up the user can't continue those action.

For ex:

The user selects 3 records, in one of this records there's a field with a certain choice than he souldn't be able to go on. So after he selects, from the 'action on selected row' below on the list, a specific action, this popup shows saying like "This X is not a control, you can't create/do this action" and doesn't let make the action.

How could I do it? With a script include? Is there a glide that I can use for it?

Someone can show me a draft of how the script should look?

Hope you can help me,

Thanks

on which UI action you want this?

@Ankur Bawiskar I want that the popup appear and stop the action after selected one of the choice below the list as you can see in the image.

So I should selected some records, click one of the choice and if not respect some conditions it should show the popup alert

the code for Action on selected rows is not accessible to admins/developers.

So you cannot customize it.

Anyhow for list choice UI action the script will only run for the records which satisfy the UI action condition

@Ankur Bawiskar ok, but I don't want to change the action on selected rows,  I would use it like the trigger for the popup if users selected the wrong records.

In any case I could I make a popup message appear on a record lists? There's some script I could use for that? I have to create them as script includes?

Thanks
