Field plug-in feature demo: metadata

Description

This field plug-in is meant to demonstrate how to use field metadata. It adds a second input box below the regular text input, which will store metadata. This value is stored separately from the field's response. From the developer documentation for field plug-ins:

Your field plug-in can store metadata alongside response data. This metadata can be accessed by other fields in the form using the plug-in-metadata(field) function. This can be used to pass information from your field plug-in to other parts of the form. See this page for more info about form functions including plug-in-metadata(field).

Note: this field plug-in is not intended to be used to collect actual data. It is intended for demonstration/testing purposes.
