Sometimes if I open a dialog this dialog is larger then the vertical height of the screen but there is not a vertical scrollbar visible.
I know its possible to set a fixed height but the contents of this dialog is variable and a large dialog with a small form looks strange
The dialog height/width can be set in percent as well.
The height of the dialog is automatic but depending on the content can be larger then the screen. If that is the case there is no scrollbar visible. That is my problem.
(sorry for fuzy explaination)
We are still not sure what scrollbar you are referring to. Can you attach a screenshot?
This is intentional as otherwise scrolling on mobile devices or the mouse scroll button will scroll the browser and not the dialog.
In this case better UX is the dialog to have scrollbars itself. And this is what normally happens.
Thank you for your quick response 
I think the scrollbar in de modal is shown because you set the height option of the dialog. Would it be possible to not set the height option but show the scrollbar (in the dialog) if the content is larger then the viewscreen ?
In my case the content of the popup is variable.
The example I've shown does not set the height of the dialog.
