Url for type
From Shopify Wiki
url_for_type(type)
This filter creates an url for a type name by URL-encoding the type name and adding the appropriate directory in front of it to make the url work.
{{ "Used car" | url_for_type }}
The previous example would result in an output like this:
"collections/types?q=Used+car"
You will most likely want to use link_to_type instead.
