I had what I thought was a very simple issue: Select some categories on the front-end, filtering by a Checkbox field.
The Checkbox has values, which correlate to Locales.
The end goal was to create a 'workaround' to the fact that you can't disable/enable a category per Locale.
So on the template, I attempted:
{% for collection in craft.categories.group('dressCollection').regionAvailability(craft.locale) %}
But that doesn't work.
