Doesn't allow null

[patrikalienus]

Perhaps this isn't an Issue per se, but since the field does not allow a null selection, a slider will always be chosen. I'd like the ability for it to be empty. Otherwise I have to add a conditional in a more obtrusive way.

Instead of if (get_field('slider')) { ... }
I have to use a true/false field to check whether it should be displayed or not:
if (get_field('use_slider' == true)) { ... }

Just a hassle...
