问题
I have 3 suppliers, 40 brands and 120 products, all displayed in three category filters. When a user selects one supplier from the Supplier filter, I want the Brand filter to hide all brands that are not provided by that supplier. Likewise, when a brand is selected, I want to hide the irrelevant products from the Products filter. I don't really care about what's being shown in the table at this point.
Is there any way to implement something like this?

Heres an example for you -

You can do this by creating a Dashboard. At around line 61 you can see that the selection made in the 'Sex' drop down is bound to the 'Name' dropdown, thus limiting what Names can be selected.
dashboard.bind(filterSex, filterName);
dashboard.bind(filterSex, pieChart);
