I am using UI for ASP.NET MVC R3 2016 and I have enabled the column menu to allow for showing/hiding of columns. That resulted in the filter getting moved into this menu as well. I'm not crazy about that, but I could accept that if the filtering worked in the column menu. The problem is I can't just open the column menu, open filter and click on the textbox in the filter menu, the entire thing closes. However, if I first select a type of filter (starts with, etc.) and then go to the textbox it works. While it is a workaround it is not an acceptable one. The problem exists in Chrome but in Edge it seems to behave correctly.
This behavior can be observed by going to http://demos.telerik.com/kendo-ui/grid/column-menu. Try to filter on Ship Name without first selecting a filter type.
