I have developed an application in Oracle Apex where we linked multiple pages through buttons click, I am able to link multiple pages by clicking different buttons but problem is that when child pages are opening by clicking the button..child pages are hiding the main page content and then I have to drag child page to reach/see to main page content.. can you please help me to implement Cascading feature on apex pages where child page will open on top of base/main page and every child page size will be little less then main page OR child page will consume half or one forth of the screen size and I should be able to set the position of child page (top right , top left, in middle ) so that I can see 2 or 3 pages on same issue rather then minimizing or dragging child page to see content of base page.. Thank you
