 * The cascader component is a Select with a cascading flyout menu. When you have lots of options in your select, they can be hard to navigate from a regular dropdown list. In that case you can use the cascader to organize your options into groups hierarchically. Just like in the Select component, the cascader input doubles as a search field to quickly jump to a selection without navigating the list.
