Where do you set the 'Visible When' condition for a layout based on a button click?

The 'Visible When' condition can indeed be set on either the button or the layout, providing flexibility in controlling visibility based on user interactions. When the condition is applied to the button, it allows the button itself to determine the visibility of the layout it influences. This means that the layout can remain hidden until the user clicks the button, at which point the layout's visibility condition becomes true.

Alternatively, setting the condition directly on the layout allows for broader control, as it can respond to variables or parameters that might not be directly linked to the button's action. By allowing visibility conditions to be placed on either component, Pega facilitates diverse use cases, such as showing different layouts based on different triggers.

This dual capability enhances the user experience by providing a responsive interface that adapts to user actions, aligning with the principles of dynamic application development in Pega.
