I understand. So the only way to do so is by adding a boolean field just before and condition range field visibility on it.
Thanks John for your answers
Hello,
Min: -50
Max: 50
Step: 5
Required: no
Default value: empty
There’s no validation error, but since I don’t set any default value and field is not required, I assume that when field is empty, it should NOT be treated as field with explicit 0 value.
That’s what I need to distinguish.
For now, when submitting article, the empty range fields get 0 value.
