This example demonstrates the 2-step filter. In this demo, however, we open one group by default and keep all others hidden. The logical operator is by default “IN”, so every post that has at least one tag among the selected tags will be displayed. The “static taxonomy” restricts the filter on a category that contains only sample posts.
