State button is not only a button. Sure you can use state button as a typical button but you can do so much more with this awesome widget. A lot of the time we need to add some multiple elements in one single group. You may try doing it but hitting Ctrl/Cmd + G but that do not make those elements into one parent. To do that you can use state button neatly. You an drop as many content as you need in to a state button and they will act as one single element.
