What problem does it solve?

The Dropdown Tree control condenses hierarchical datasets into a compact, searchable dropdown so users can select single or multiple nested items without building custom tree UI or loading entire datasets upfront.

Core Features & Use Cases

• Hierarchical selection: map nested or self-referential data to present parent/child relationships in a dropdown.
• Multi-select with checkboxes: enable showCheckBox, Select All, and auto-check propagation for parent-child dependency.
• Performance & lazy loading: support DataManager and loadOnDemand for large datasets to minimize initial payload.
• Templates & customization: item, value, header, footer, no-records, and action-failure templates for tailored rendering.
• Filtering, sorting, and accessibility: built-in filtering options, keyboard navigation, ARIA attributes, and localization support.
• Programmatic APIs & events: methods for appendTo, showPopup/hidePopup, get/set value, refresh, selectAll, and events like change, dataBound, and filtering.

Quick Start

Create a DropDownTree bound to your hierarchical data, enable checkboxes or loadOnDemand as required, and render it into the input element with id ddtElement.
