Description & Source Code

The master detail feature allows a grid to behave like a tree, allowing a row to expand and show more details with respect to the row item.

Using <detail>, developers can embed detailed content (other ZK components) enclosed by it, and it is allowed to be expanded or collapsed to show/hide the detailed content.
