This element allows the display of options that can be expanded with one click. 

Allow scrolling

If the content elements within the container require more space than is available due to their position and size, they are truncated when the checkbox is deactivated. If the checkbox is enabled, scrollbars are displayed on the right and bottom sides when the container limits are exceeded. These are displayed on the inside of the container, obscuring content that can then only be reached by scrolling.

Foreground color, size and radius control the appearance of the displayed scrollbar.
