Hi
I found a bug, when having a multi select DropDownList inside a Toolbar.
See this fiddle http://jsfiddle.net/Lf3wrycj/3/
Try and select an option. Now make the window smaller so that the burger menu appears. Open the DropDownList from the burger menu and see that your selection did not work for the “burger” version of the DropDownList.
We just upgraded jQX in the hopes you would have solved these kinds of problems. Right now I made my own hack to update the burger DropDownList, but it should really work out of the box.
Kind regards,
Mick
