I have a view that shows commerce products, with an exposed filter to show only items with stock >= 0. So, if the checkbox is checked, it will hide out-of-stock items.
I would like to reverse this so that if the checkbox is checked, all items are shown, and if it is not checked, only the filtered items (stock >= 0) are shown.
The label could then be changed to "Reveal items that are currently not available".
Any idea how to do this? I could probably do this with some hook_form_alter() and stuff, but I am more interested in something to configure with the Views UI.
(Not that I shy away from custom modules in general, but I like to avoid stuff that is hardcoded to one specific view name and display id and field name..)
