Add another (experimental)
The "add another" component lets users input multiple values for a set of form fields.
This component is currently experimental because more research is needed to validate it.
Applications using this component must include a deletion checkbox in addtion to the rendered repeating items as well as an empty field. The checkboxes and empty field are required to allow users without javascript to add new items and remove existing items from the list. See the examples below for how to do this.
The example here passes HTML in to the component due to limitations in the format of this documentation. In applications it is expected that the caller will render other components instead. See Whitehall for examples of this approach.
