Link to type

From Shopify Wiki

link_to_type(type)

This filter creates a link to the label of the type with the name that has been given as a parameter.

{{ "DVD" | link_to_type }}

would create a link called "DVD" and when people click on it, they will see the label page of the label/type "DVD" which is in the most cases a list of all products in the store that have the type "DVD" (depending on the implementation of label.liquid).
