Defines the overflow mode. The available options are:

• "menu" — Moves overflowing items into a dropdown menu.
• "scroll" — Keeps items visible and enables horizontal scrolling.
• "section" — Groups items into collapsible sections.
• "none" — Disables overflow handling; items may be cut off.

The new Sort, Filter, ColumnChooser tools will not work as expected with the menu option. Currently these tools are not supported by the overflow menu. It is recomended to use the scroll options when using any of these tools.
