Hi @nuttakit,

What you can do is add an event listener on the annotationFilterChanged event. And anytime the event is fired, you can then programatically get all the annotations from the annotation manager and hide the ones that match the filter. When your filter is cleared you can then show all annotations.

Here are some relevant APIs that will help you:
