How to add map to collection page

Using Omeka 2.3 and Geolocation 2.2.3, we would like to add the map for all the items in a collection to the collection page. Is this possible?

You can do that by editing your theme and adding a geolocation map to the collections/show page.

The easiest way is probably to use the existing geolocation shortcode, which provides a collection option, and the shortcodes view helper.
