streamlit tree independent components

Component is React component designed to render a hierarchical tree view with checkboxes, integrated with Streamlit for use within Streamlit applications. It allows users to navigate and select items in a nested structure, with customizable icons and state management features.

Features

Hierarchical Tree Structure:

Renders a nested tree structure using TreeView and TreeItem from Material-UI. Nodes can have multiple child nodes, creating a multi-level hierarchy. Checkbox Selection:

Each node includes a checkbox for selection.

The component manages the selection state, ensuring it reflects the user's choices. Node Icon Customization:

Nodes can display different icons based on their type (folder, settings, document, or a default file icon).

Icons are determined using the determineIcon function.

Disabled Nodes: Nodes can be marked as disabled using the disable property. Disabled nodes are visually distinct (grayed out) and cannot be selected. The component skips these nodes when managing state changes and rendering. Parent-Child Relationship Management:

Includes functions (getChildById and findParentById) to manage selection states across parent and child nodes.

Ensures consistent selection/deselection of parent and child nodes.

State Management: Manages the state using selected (to track selected nodes) and setSelected. State updates occur whenever a user interacts with the component.

Integration with Streamlit:

Uses StreamlitComponentBase and the Streamlit API for seamless integration with Streamlit apps. Sends updated state back to the Streamlit environment for dynamic interactions. Recursive Rendering:

The renderTree method handles recursive rendering of the tree structure, ensuring all child nodes are displayed correctly.

Expandable Nodes: Includes icons for expanding (ExpandMoreIcon) and collapsing (ChevronRightIcon) nodes, enhancing navigation through the tree.
