Footer of mainwindow

Hi There,

I'm displaying some standard text in footer of Main window. Which I expect to display it after the main item of main window, which works good.

Now the problem is, I have another window right below the main window. The text of main window footer is overlapping, with the text of window which is right below the main window.

I have marked the down window to display only after the end of main window , but still I see the footer(of Main window) overlapping with the secordary window text.

Expectation: If there is no enough space for secondary window, it should display in next page.

Kindly advise me how to achieve this.

Red box: Item Details

Black box: Footer

Green box: Secondary window text

Thanks,

Priya
