In this demo, you can drag our Toolbar container's resizing handle to visualize resize operations and view our rendering implementation on different screens. When used in single-line mode (default), our Toolbar does not wrap content and displays an overflow menu for items that do not fit within the container. Use the locateInMenu property to control whether items appear in the overflow menu.

If Toolbar width exceeds container width (and if you enable the component’s multiline property), our Toolbar wraps content across multiple lines.
