Visualizing Hierarchical Data with the Tree Component
The Tree component represents nested categories, folders, or organizational structures, allowing users to explore complex data relationships.
Features
Discover the key features of the Tree component.
Hierarchical Content Organization
Trees organize information into a hierarchical structure, facilitating navigation and understanding. Enhance user experience with intuitive tree-based content organization.
Visual Representation of Relationships
Nodes and branches visually represent relationships between elements, aiding users in comprehending complex data structures. Improve user engagement with clear visual hierarchies.
Interactive Exploration
Users can expand and collapse tree nodes, enabling interactive exploration of nested content. Enhance user experience with dynamic tree navigation for seamless information access.
Anatomy
Icons
Each level features two distinctive icons which visually represent the category or option presented, assisting in quick recognition and navigation.
Supporting Text
Accompanying the icons is the supporting text, which provides further clarification or description pertaining to the category or option represented by the icons.
Example Use Cases
Navigation
Users can navigate through the hierarchical structure of data by expanding or collapsing nodes within the tree. This enables them to explore different levels of detail and find specific items or categories of interest.
Organization
The Tree component is effective for organizing and presenting hierarchical data, such as file directories, organizational charts, or product categories. It helps users understand the relationships between different entities and facilitates efficient information retrieval.
Selection
Users can select individual nodes within the tree to perform actions or view additional details. Selected nodes may trigger context menus, open modal dialogs, or display supplementary information in adjacent panels.
Interactivity
The Tree component often supports interactive features such as drag-and-drop functionality for reordering nodes, context menus for performing actions on nodes, and keyboard shortcuts for navigating the tree.
Guidelines for Usage
When incorporating the Tree component into a user interface, consider the following guidelines to ensure optimal usability and user experience:
Clear Hierarchical Structure: Organize the tree nodes in a logical hierarchy that reflects the underlying data structure. Use indentation, icons, or visual cues to indicate parent-child relationships and distinguish between different levels of the hierarchy.
Concise Labels: Use concise and descriptive labels for tree nodes to convey relevant information about each item. Avoid overly long or ambiguous labels that may clutter the interface or confuse users.
Responsive Design: Design the Tree component to be responsive and adaptable to different screen sizes and resolutions. Ensure that the tree layout remains legible and usable on both desktop and mobile devices.
Performance Optimization: Optimize the performance of the Tree component, especially when dealing with large datasets or deeply nested hierarchies. Implement features such as lazy loading or virtual scrolling to improve rendering speed and minimize resource consumption.
Variants
.tree-primary
The main style for the component, often used for primary actions or the most important interactions, typically featuring bold colors and a solid background to stand out.
.tree-secondary
A less prominent style for the component, used for secondary actions or supplementary interactions, often with a more subdued color palette and less emphasis.
Levels
It consists of three differentiated levels – First, Second, and Third. Each subsequent level offers a deeper insight or categorization than its predecessor, aiding in streamlined navigation.
.tree-first
First level, or first starting point of tree.
.tree-second
Shifted to the right with left padding of 40px.
.tree-third
Shifted to the right with left padding of 64px.
States
.tree :enabled
The default state where the component is fully interactive and ready for user actions. It appears normal and invites interaction.
.tree :hover
The state when a user places their cursor over the component, indicating it is ready for interaction and often visually changes to show responsiveness.
.tree :focus
The state showing that the component is currently selected or active, highlighted for user awareness and accessibility purposes, often with a border or shadow.
.tree :*disabled
The state where the component is visible but non-interactive, indicating it is not available for use. It often appears faded or greyed out to signal its inactivity.
Best Practices vs. Common Pitfalls
Do:
Maintain a consistent visual language with the use of predefined icon instances, ensuring a harmonious and unified design.
Use clear and concise supporting text to aid in navigation and understanding, fostering a user-friendly experience.
Utilize the various states (enabled, hover, focus, disabled) to craft a responsive and interactive navigation tool.
Don't:
Avoid cluttering each level with excessive information or icons, which can lead to a convoluted and confusing user experience.
Do not neglect the visual hierarchy between levels, which helps in establishing a clear and structured navigation pathway.
Avoid using disparate icon styles or instances outside of the predefined set, which can disrupt the visual harmony and coherence of the component.
