Dynamic action - Fire on page load
Fire on Page load is an option available on each TRUE/FALSE sub-action as part of a Dynamic Action. I am not sure I understand how this is useful. By definition, a dynamic action is triggered by some sort of user interaction like clicking or hovering and such. So how could it be triggered when the page is simply loaded? Even so, why is this option available on each "sub-action" and not on the main DA properties itself? So if a DA has 4 TRUE actions, under what circumstances would one want some of them to fire on page load but not others?
What am I missing?
