# XWUIDashboardDrilldownTable

A hierarchical table for drilling into aggregated metrics. Rows can nest children, expand and collapse with indentation showing depth, and numeric columns automatically roll up into a subtree total whenever a parent is collapsed.

## Basic Usage

Regional sales rolled up through country and city; collapsed parents show subtree totals.

## Interactive Drilldown

External toolbar drives expandAll/collapseAll, and clicking a row label reports its id path.
