You can use the`total-visible` prop to limit the visible items. Items that exceed limit are displayed after clicking on "..." item. The default behavior can be changed with`collapse-in-menu` to display the collapsed items inside a dropdown menu.

You can also use the`collapse-from` prop to control how many leading items remain visible before collapsing items.
