Disable Close prevents the reader from closing a pop-up box and can be found in the settings for selected interactive items.
To access the section, select a piece of interactivity that you have added to your page followed by the Settings palette.
How does it work?
Disable Close works by removing the cross from the top right corner and stops the pop-up closing if the greyed out area around the popup is clicked.
This effectively makes the pop-up mandatory as it requires the reader to complete a task that allows them to close the pop-up.
How do I set this up?
Select the piece of interactivity on your page followed by the Settings palette. Tick the Disable Close checkbox under Pop-up Style.
