Definition and Usage

TreeView:

• Definition: A TreeView is a hierarchical list or tree structure that allows users to view, navigate, and select items from nested lists or categories.
• Usage: Commonly used in file explorers, settings menus, and organizational charts. It provides a visual representation of hierarchical data, allowing users to expand or collapse branches to view or hide sub-items.

Basic Component

Usability

Intuitive Hierarchical Structure

A well-designed tree view component should present data in a clear and intuitive hierarchical structure. Users should easily understand the relationships between parent and child items, enhancing usability.

Expand and Collapse Functionality

Usability is improved when users can expand and collapse tree nodes to reveal or hide sub-level information. This feature simplifies navigation within large data sets.

Drag-and-Drop Support

The ability to drag and drop items within the tree view enhances usability, allowing users to reorder or organize items effortlessly.

User-Friendly Icons and Symbols

Icons or symbols used to represent different types of tree nodes should be easily understandable, aiding usability. For example, using a folder icon for directories is a widely recognized convention.

Accessibility

Keyboard Navigation

Keyboard navigation is critical for accessibility. All interactive elements, including tree nodes and expand/collapse controls, should be operable using keyboard commands.
