screen painter: cannot add fields to subscreen
I use screen painter to create a screen. Only when a checkbox is ticked, will a subscreen pop up including text fields and input/output fields. But fields cannot be added to the Subscreen Area. The message wites 'Collision at target location (element not placed)'. Do I have to hard code to control the visibility of the subscreen under the condition I mentioned above? Where can I write code to check the condition for the subscreen to diaplay?
