+ *
+ * Use `[menuLust]=myArray` and `(ellipsisMenuItem)=myFunction($event)` if a menu is needed
+ *

+ * ### Usage of the selector:

+ * <app-head-bar

+ *   PlusButton=true
+ *   [menuList]=myMenu
+ *   (plusButtonClicked)=onPlusButton()

+ *   {
+ *     text: 'Download All',
+ *     icon: 'download',
+ *     action: 'downloadAllFiles'
+ *   },
