I'm creating a view. By default, I want all results shown, with an exposed filter for 'has a value' (aka is not empty) and 'is empty'.
I cannot figure out how to make the exposed filter work for this. If I make the exposed filter on either 'is empty' or 'is not empty', it filters the values initially based on that section. I only want the exposed filter to take effect when the value is in the URL.
Can anyone point me how to do that?
