Registration Client UI Specifications
Overview
The registration UI forms are rendered using respective UI specification JSON. This is derived from the ID Schema defined by a country. Here, we would be discussing about the properties used in the UI specification of Registration Client.
In the Registration Client, currently, Registration Tasks(process) forms are configurable using the UI specifications.
Each process has multiple screens and each screen is rendered with one or more fields.
