TreeSidebar Component

A hierarchical tree navigation component for rendering nested scope/node structures with expandable sections, search, and configurable actions. The component is part of the @e-llm-studio/creative-workspace-ui-component package and can be used independently in any React application.

Introduction

TreeSidebar is a standalone component from the @e-llm-studio/creative-workspace-ui-component package designed to provide a fully generic, hierarchical tree navigation panel. Its primary purpose is to render a tree of nodes (e.g. Global → Scope → Subscope) with expandable sections, search filtering, and optional action handlers. The consuming team controls what actions are available by passing or omitting handler props — if a handler is not passed, the corresponding button is not rendered.

Features

• Hierarchical tree rendering — Supports unlimited nesting levels (Global → Scope → Subscope → ...)
• Expand/collapse — Each node is independently expandable; root node auto-expands on load
• Section items — Each node can show configurable section tabs (e.g. Learnings, Stations) below it when expanded
• Search filtering — Pass a searchQuery to filter nodes by name; non-matching subtrees are hidden
• Configurable node types — Control labels, add-child labels and child types via nodeTypesConfig
• Configurable sections — Control which sections appear per node via sectionsConfig
• Conditional actions — Add, Rename, Delete buttons only render when the corresponding handler prop is passed
• Children count badge — Optional badge showing number of direct children per node
• Section badge — Optional badge on section items showing metrics (e.g. learnings count)
• Inline styles only — No Tailwind or MUI dependency, works in any consuming app regardless of styling setup

Installation

The TreeSidebar component is part of the @e-llm-studio/creative-workspace-ui-component package.

Using npm

npm install @e-llm-studio/creative-workspace-ui-component

Using yarn

yarn add @e-llm-studio/creative-workspace-ui-component

Import Statement

import { TreeSidebar } from "@e-llm-studio/creative-workspace-ui-component";
// or via subpath
import { TreeSidebar } from "@e-llm-studio/creative-workspace-ui-component/TreeSidebar";

Usage

Basic Example

Here's a simple example demonstrating how to use TreeSidebar with minimal props:

import { TreeSidebar } from "@e-llm-studio/creative-workspace-ui-component";
import { BookOpen } from "lucide-react";

const treeData = {
  id: "root",
  name: "Global Scope",
  type: "GLOBAL" as const,
  metrics: { learningsCount: 10 },
  children: [
    {
      id: "scope-1",
      name: "Scope 1",
      type: "SCOPE" as const,
      metrics: { learningsCount: 5 },
      children: [],
    },
  ],
};

export default function App() {
  return (
    <TreeSidebar
      data={treeData}
      sectionsConfig={[
        {
          id: "learnings",
          label: "Learnings",
          icon: BookOpen,
          badgeKey: "learningsCount",
        },
      ]}
      nodeTypesConfig={[
        { type: "GLOBAL", label: "Global", addChildLabel: "Add Scope", addChildType: "SCOPE" },
        { type: "SCOPE", label: "Scope" },
      ]}
      onSectionSelect={(nodeId, sectionId) => console.log(nodeId, sectionId)}
    />
  );
}

Key Props Explained:

• data: The root node of the tree — pass null to render nothing
• sectionsConfig: Defines which section tabs appear under each expanded node
• nodeTypesConfig: Defines node labels and add-child behavior per depth level
• onSectionSelect: Fired when a section tab is clicked — returns the selected nodeId and sectionId

Advanced Example

This example demonstrates all action handlers and badge visibility controls:

import { TreeSidebar } from "@e-llm-studio/creative-workspace-ui-component";
import { BookOpen } from "lucide-react";

export default function AdvancedExample() {
  return (
    <TreeSidebar
      data={treeData}
      sectionsConfig={[
        {
          id: "learnings",
          label: "Learnings",
          icon: BookOpen,
          badgeKey: "learningsCount",
        },
      ]}
      nodeTypesConfig={[
        { type: "GLOBAL", label: "Global", addChildLabel: "Add Scope", addChildType: "SCOPE" },
        { type: "SCOPE", label: "Scope" },
      ]}
      onSectionSelect={(nodeId, sectionId) => handleSelect(nodeId, sectionId)}
      onAddChild={(parentId, childType, parentName) => handleAdd(parentId, childType, parentName)}
      onRenameChild={(scopeId, initialName) => handleRename(scopeId, initialName)}
      onDeleteChild={(scopeId, scopeName, learningsCount) => handleDelete(scopeId, scopeName, learningsCount)}
      showChildrenCount={true}
      showSectionBadge={true}
    />
  );
}

Customization Tips:

• Only pass the action handlers (onAddChild, onRenameChild, onDeleteChild) your use case needs — unneeded buttons won't render
• Use showChildrenCount={false} to hide the children count badge on node headers
• Use showSectionBadge={false} to hide the metric badge on section items
• Use searchQuery with onSearchCountChange to implement a search bar above the tree

Examples

With search

const [searchQuery, setSearchQuery] = useState('');
const [searchCount, setSearchCount] = useState(0);

<>
  <input
    value={searchQuery}
    onChange={(e) => setSearchQuery(e.target.value)}
    placeholder="Search scopes..."
  />
  <span>{searchCount} results</span>
  <TreeSidebar
    data={treeData}
    sectionsConfig={sectionsConfig}
    nodeTypesConfig={nodeTypesConfig}
    searchQuery={searchQuery}
    onSearchCountChange={setSearchCount}
  />
</>

With only rename and delete (no add)

<TreeSidebar
  data={treeData}
  sectionsConfig={sectionsConfig}
  nodeTypesConfig={nodeTypesConfig}
  onRenameChild={(scopeId, name) => handleRename(scopeId, name)}
  onDeleteChild={(scopeId, name, count) => handleDelete(scopeId, name, count)}
/>

With badges hidden

<TreeSidebar
  data={treeData}
  sectionsConfig={sectionsConfig}
  nodeTypesConfig={nodeTypesConfig}
  showChildrenCount={false}
  showSectionBadge={false}
/>

With auto-selected node

<TreeSidebar
  data={treeData}
  sectionsConfig={sectionsConfig}
  nodeTypesConfig={nodeTypesConfig}
  selectedRuleSetId="scope-1"
  activeSectionId="learnings"
/>

With multiple sections

import { BookOpen, RadioTower } from 'lucide-react';

<TreeSidebar
  data={treeData}
  sectionsConfig={[
    { id: 'learnings', label: 'Learnings', icon: BookOpen, badgeKey: 'learningsCount' },
    {
      id: 'stations',
      label: 'Stations',
      icon: RadioTower,
      badgeKey: 'stationsCount',
      isVisible: (node, depth) => depth > 0, // Only show for non-root nodes
    },
  ]}
  nodeTypesConfig={nodeTypesConfig}
/>

Notes

• TreeSidebar is display-only — no internal data fetching. All state and data management lives in the consuming app.
• Action buttons (Add, Rename, Delete) are conditionally rendered — only shown when the corresponding handler prop is passed.
• The nodeTypesConfig array maps to tree depth — index 0 applies to the root node, index 1 to its children, and so on. If the tree is deeper than the config array, the last config entry is reused.
• Delete is automatically disabled for nodes that have children, with a tooltip explaining why.
• The root node auto-expands on load and whenever data changes.
• Search expansion is automatic — all ancestor nodes of matching results are expanded.
