Master-Detail Style Apps with Variables & Events

    Initially, this feature was planned to follow the basics of the Master-detail design interface. But it evolved into something much more. We are all familiar with the essence of the Master-detail pattern, it is a way to present a list of records and enable the user to manage them with ease. It usually comprises two views - One is the master list of records and the other is used to display extended data about a single record.

    Key Elements of the Master-Detail Pattern in App Builder

    The new feature covers these key elements established by the Master-detail pattern:

    • Primary Pane: This area displays a list of items or triggers that initiate the loading of other app components.
    • Details Pane: It shows detailed information about the item selected in the Primary pane, utilizing various interactive components.
    • Interactions: These define how the master list and detail views interact, including context, drill-downs, and pop-ups.
