I want my filters to update and only show options that match up with all filters currently applied.
I am working with Year Make Model filters. If I select a year 2004 and apply that filter. I want the Make and Model filters to only show the currently filtered data set options. I should only see Make and Model options that have a year of 2004.
In addition, after the first init call of the filter, i want the options to reload based on the data source. If I add a new car to the data source or remove one, the filter options will re-poll the data source and find those ones removed or added.
"define one DataSource instance and assign it to both the Grid and in columns.filterable.dataSource. This will refresh the checkbox data automatically, but if you filter the Grid data via the Grid UI, you will also filter (reduce) the checkbox items."
