Popups (Modal Screens)
A popup, also called a modal screen, is a smaller screen that appears within another screen.

An example of this type of screen is the Search popup that opens when adding a new entity.
Popups typically display the following buttons:
New—Creates a new record.
Add Selected—Adds the data you have selected from the list to a record.
Add Selected and Close—Adds all data you have selected from the list to a record and closes the popup.
Close—Closes the popup.
