Sometimes, if we end with a sidebar with a large amount of items, it would be useful to visually separate them in groups taking into account their context. In this situation, the divider order-item property becomes a handy feature.
Since the beginning it is possible to assign the href of a sidebar item specificing this property. This property is useful if one wants to go to a dashboard or open an external website when clicking on sidebar items. But since some time, it is also possible to execute a Home Assistant Service (renamed recently to Actions) if we specify the correct action in the on_click proprty of a sidebar item.
Since some time already, it is possible to add templates to the hide property of the order items. This means that it is possible to show or hide items when the state of an entity changes.
