The Content Lake Listing is used to display content lake items in two or three columns. It contains a search box, search filter, show more button and a view count. This rendering is driven by the Content Lake Taxonomy - categories, tags, region, author - and it dynamically pulls content items from the Content Lake, which are tagged accordingly. 

Note: No content lake listing results will appear in the Experience Editor since the component does not fire javascript search queries in the Experience Editor.
