select_filter successive filtering?

Is there a way to have successive filtering on select_filters, similar to how it is done in Excel?



For instance, if I filter the contents of the grid, the filters would be updated so that they are only valid for what the user can currently see in the grid.



Is there a way to do that or is that something I would have to write custom code for (loop through contents of grid and update select filter values appropriately)? It would be a really useful feature for grids with a lot of data.

Unfortunately there is no such inbuild functionality but you can create any custom filter you need. Please find more information here dhtmlx.com/docs/products/dhtmlxG … grid_fsing.
To get instance of the filter object you can use getFilterElement(index) method where index - index of column.
