The Angular CDK (Component Dev Kit) provides behavior primitives for building custom UI components without Material Design styling.

Key CDK modules:
- Overlay: Create floating panels, tooltips, dropdown menus
- Drag and Drop: Sortable lists and drag operations
- Virtual Scrolling: Render only visible items for huge lists
- Clipboard: Copy text to clipboard
- Portal: Render templates into different DOM locations
- Layout: Responsive breakpoint detection

Overlay module highlights:
- Position strategies for floating elements
- Scroll strategies (close, block, reposition)
- Backdrop support for modals
- Keyboard and focus management

Drag and Drop:
- Reorderable lists with cdkDropList
- Transfer items between lists
- Custom drag previews and placeholders
- Boundary restrictions for drag area

Virtual Scrolling:
- Render thousands of items without performance issues
- Fixed and auto-size strategies
- Custom item heights supported

The CDK is the foundation Angular Material is built on. Use it to create custom component libraries. What CDK features do you use?

The CDK is an underrated gem in the Angular ecosystem. The Overlay module alone saves hours of custom positioning logic, and Virtual Scrolling is a must for rendering large datasets. Drag and Drop with cdkDropList is incredibly smooth. Every Angular developer should explore CDK before reaching for third-party UI libraries.
