Hello Experts,

In traditional UI (section-based) Pega applications, we often use the Master–Detail flow action display pattern, where the primary (master) content is shown on one side and the details of the selected item are displayed on the other.

I am looking for the Constellation design system equivalent of this approach, with the following requirements:

• The master screen itself should remain editable (not just read-only).

• Details of the selected record should be shown alongside the master.

• Ideally, the user should be able to work with both master and detail in a single seamless interaction.

My questions are:

1. Which Constellation components or patterns best support this requirement?

2. Is there a recommended best practice for editable master–detail interaction in Constellation?

3. If no direct equivalent exists, what’s the closest supported design alternative?

I’ve attached screenshots from the traditional environment for reference.

Thanks in advance for your guidance!
