 -- `NonEmptyFormFieldDependency` can be used to ensure that a node is only shown if the value of the referenced form field is not empty (being empty is determined using PHP’s `empty()` language construct).
 -- `EmptyFormFieldDependency` is the inverse of `NonEmptyFormFieldDependency`, checking for `!empty()`.
 -- `ValueFormFieldDependency` can be used to ensure that a node is only shown if the value of the referenced form field is from a specified list of of values (see methods `values($values)` and `getValues()`).

 +`ValueFormFieldDependency` can be used to ensure that a node is only shown if the value of the referenced form field is from a specified list of of values (see methods `values($values)` and `getValues()`).
    Additionally, via `negate($negate = true)` and `isNegated()`, the logic can also be inverted by requiring the value of the referenced form field not to be from a specified list of values.
  
 +### `ValueIntervalFormFieldDependency`
 +
 +!!! info "Only available since version 5.5."
 +
 +`ValueIntervalFormFieldDependency` can be used to ensure that a node is only shown if the value of the referenced form field is in a specific interval whose boundaries are set via `minimum(?float $minimum = null)` and `maximum(?float $maximum = null)`.
