Description and Notes

The Conditional Fields Module module implements functionality that makes it possible to conditionally control a field's appearance. For example image a multi-select field with an other choice that includes an optional text field for providing additional, other, information. With the module, the other text field can be set to appear only when the user selects other from the list of options above it.
