Hi,
We just noticed that the subcategories dropdown list now only has a ‘none’ option where it used to also have an ‘all’ option.
Here’s what it looks like now:
Here’s what it looks like on an older installation:
While ‘all’ is still the default value, you can’t return to it after diving into a subcategory, making navigation a little harder. Is this on purpose, or a bug?
Good catch, don’t think this is intentional. If you need to get to “all” you can select “none” first, then reopen the filter.
This should fix it, it also introduces tests for category-drop:

Will think more about it and maybe improve it more and push it Monday.
Looking good to me, thanks @joffreyjaffeux. All set here @bartv?
Yep, it works fine for me too. Thanks for the quick solution everyone!
