This sample demonstrates the way of data binding in
menu using hover / click action.
The menu component loads the data through the items property, where the data can either be structured as hierarchical or self-referential data, i.e. mapped with id and parentId fields. In this demo, the component is bound with the list type data where the parent-child relation is referred by id and parentId mapping fields. More information about menu can be found in this data binding section.
