SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

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.

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I implement hierarchical dropdown tree selection in JavaScript for nested data?▼

Hierarchical dropdown tree selection maps nested or self-referential data into a compact dropdown UI, allowing users to select single or multiple items from parent-child relationships without building custom tree components.

How does lazy loading work for large datasets in a dropdown tree component?▼

Lazy loading uses loadOnDemand with DataManager to fetch child nodes only when expanded, minimizing the initial payload for large hierarchical datasets and improving overall page performance.

Can I enable multi-select checkboxes with auto-check propagation for parent-child nodes?▼

Multi-select checkboxes enable parent-child auto-check propagation, so selecting a parent automatically checks all children, while a Select All option provides bulk selection for the entire tree.

What templates are available for customizing dropdown tree item rendering?▼

Customizable templates include item, value, header, footer, no-records, and action-failure templates, allowing tailored rendering of hierarchical nodes and popup display states.

Does the dropdown tree support filtering and keyboard navigation for accessibility?▼

Built-in filtering options, keyboard navigation, ARIA attributes, and localization support ensure the dropdown tree is accessible and searchable for users navigating hierarchical data.

What programmatic APIs are available for managing popup and value states?▼

Programmatic APIs include methods for showPopup, hidePopup, get and set value, refresh, and selectAll, alongside events like change, dataBound, and filtering for granular control over the dropdown tree.
