I'm working with grids that have a lot of columns. Using your latest version (2017.3.1026), the 'Columns' menu for any column that is also filterable can no longer be scrolled using a trackpad or scroll wheel. The dojo example below was copied from the column menu demo: http://demos.telerik.com/kendo-ui/grid/column-menu but more columns were added to demonstrate scrolling. The undesired behavior can be seen on the first four columns which are filterable. Beginning with the fifth column, 'Test 2', the 'filterable' property is set to 'false' and scrolling behaves as expected. This is reproducible in the latest versions of Chrome and Firefox.
