I have seen that Kanban board supports Sub Categories within a column (Category). Kanban Items can be placed in any of Sub Category. Sub Categories are becoming visible only when dragging and dropping Items. I need to display Sub Category name always so that the user viewing the Kanban board can identify the sub category an item is belonging to. I also need to be able to drag and drop items from one sub category to another within the same column (category) just like we drag and drop items from one column (category) to another. How can I achieve that?
