I have a need for a kendo grid with locked columns and a dropdown panel. I tried accomplishing this using the kendo grid's locked and detail template but this is not supported. I need to have a grid with 3 columns locked on the right that are visible regardless of screen size. These columns have the dropdown arrow, an icon, and a name. The rest of the columns should scroll horizontally when there are too many to fit on the screen. There should be a dropdown panel that opens when the user clicks the expand button. This panel should not scroll horizontally and should always be aligned with the left edge of the grid (not the left edge of the scrollable content). I need a grid because the user wants to sort the rows and search. They also want to see the data in tabular format. How would I accomplish this given that Telerik has decided not to support having locked or sticky columns and detail templates in the same grid.
