Chaining Filters

The CollectionView.filter property allows you to specify one filtering function for the collection. You can use the results of one filter to create a secondary filter.

This is called chaining and it can be done using another CollectionView, as shown in this example.

You can also use the CollectionView.filters property to add multiple filter funtions to the view. This is a new option that is usually simpler and more efficient than chaining filters.
