I just upgraded to the latest Kendo Pro: 2017.2.504. This broke our code in several places. The most significant is that setting the cssClass to 'k-separator' no longer creates a line in the menu to separate menu groups. We used to be able to add a separator like this, but it no longer works:
<
p
>let menuItem = {</
p
><
p
> text: '',</
p
><
p
> cssClass: 'k-separator',</
p
><
p
> enabled: false</
p
><
p
>}</
p
