Webiste User can filter?

In the plugin-description I read this.

Placemarks can be assigned to categories, and you can control which categories are displayed on a individual map.

My question: It is possible that the website visitors filter by multile categories them selves?
i.e.
A) region 1, B) region 2, C) region 3, etc… and
A) 0-9.999 habitants, B) 10.000-49.999 habitants, etc…..

If it is not possible do you know any other plugin that can do this?

Than you,
