Quick Start Example

Create an interactive dashboard in minutes:

import React, { useRef } from 'react';
import { DashboardLayoutComponent } from '@syncfusion/ej2-react-layouts';
import '@syncfusion/ej2-base/styles/tailwind3.css';
import '@syncfusion/ej2-react-layouts/styles/tailwind3.css';

function Dashboard() {
  const dashboardRef = useRef<DashboardLayoutComponent>(null);

  const panels = [
    {
      id: 'sales',
      header: 'Sales',
      content: '<div style="padding: 20px;">Sales data</div>',
      row: 0,
      col: 0,
      sizeX: 2,
      sizeY: 2
    },
    {
      id: 'users',
      header: 'Users',
      content: '<div style="padding: 20px;">User analytics</div>',
      row: 0,
      col: 2,
      sizeX: 2,
      sizeY: 2
    },
    {
      id: 'reports',
      header: 'Reports',
      content: '<div style="padding: 20px;">Report metrics</div>',
      row: 2,
      col: 0,
      sizeX: 4,
      sizeY: 1
    }
  ];

  return (
    <div style={{ padding: '20px' }}>
      <h1>Dashboard</h1>
      <DashboardLayoutComponent
        ref={dashboardRef}
        id='dashboard'
        columns={5}
        cellSpacing={[10, 10]}
        panels={panels}
        allowDragging={true}
        allowResizing={true}
        allowFloating={true}
        enablePersistence={true}
      >
      </DashboardLayoutComponent>
    </div>
  );
}

export default Dashboard;

Common Patterns

Pattern 1: Responsive Dashboard with Mobile Support

📖 Read: [responsive-design.md](references/responsive-design.md) for comprehensive mobile adaptation patterns

<DashboardLayoutComponent
  id='responsive-dashboard'
  columns={5}
  mediaQuery='max-width:768px'  // Single column on tablets/mobile
  cellSpacing={[10, 10]}
  allowDragging={true}
  allowResizing={true}
  panels={panels}
>
</DashboardLayoutComponent>

Key Features:

• Responsive column adjustment based on screen size
• Mobile-first design with media queries
• Touch optimization for mobile devices
• See responsive-design.md for breakpoint configuration and testing

Pattern 2: Save and Restore User Layout

📖 Read: [state-persistence.md](references/state-persistence.md) for complete state serialization and storage options

const handleSaveLayout = () => {
  const layout = dashboardRef.current?.serialize();
  localStorage.setItem('userDashboard', JSON.stringify(layout));
};

const handleRestoreLayout = () => {
  const saved = localStorage.getItem('userDashboard');
  if (saved) {
    const layout = JSON.parse(saved);
    dashboardRef.current?.removeAll();
    layout.forEach(panel => {
      dashboardRef.current?.addPanel(panel);
    });
  }
};

Key Features:

• serialize() method exports current layout state
• localStorage for client-side persistence
• See state-persistence.md for API integration, Redux/Context patterns, and auto-save

Pattern 3: Dynamic Panel Management

📖 Read: [core-functionality.md](references/core-functionality.md) for panel addition/removal and runtime management

const handleAddPanel = () => {
  dashboardRef.current?.addPanel({
    id: `panel-${Date.now()}`,
    header: 'New Panel',
    content: 'Panel content',
    row: 0,
    col: 0,
    sizeX: 2,
    sizeY: 1
  });
};

const handleRemovePanel = (panelId: string) => {
  dashboardRef.current?.removePanel(panelId);
};

Key Features:

• Runtime panel creation and deletion
• Unique panel IDs and positioning
• Event handling for panel changes
• See methods-reference.md for all available panel methods

Pattern 4: Constrained Panel Sizes

📖 Read: [cell-configuration.md](references/cell-configuration.md) and [resizing-floating.md](references/resizing-floating.md) for size constraints and resizing behavior

const constrainedPanels = [
  {
    id: 'fixed-panel',
    header: 'Fixed Size',
    row: 0,
    col: 0,
    sizeX: 2,
    sizeY: 1,
    minSizeX: 2,  // Cannot shrink
    maxSizeX: 2,  // Cannot expand
    minSizeY: 1,
    maxSizeY: 1
  },
  {
    id: 'flexible-panel',
    header: 'Flexible',
    row: 0,
    col: 2,
    sizeX: 2,
    sizeY: 1,
    minSizeX: 1,  // Can shrink to 1 cell
    maxSizeX: 4   // Can expand to 4 cells
  }
];

Key Features:

• minSizeX/Y and maxSizeX/Y constraints
• Fixed vs. flexible panel sizing
• Programmatic size updates via resizePanel()
• See cell-configuration.md for grid calculations and resizing-floating.md for advanced resize patterns

Pattern 5: Monitor Layout Changes

📖 Read: [events-reference.md](references/events-reference.md) for all available events and handlers

const handleChange = (args: ChangeEventArgs) => {
  console.log('Panels added:', args.addedPanels);
  console.log('Panels removed:', args.removedPanels);
  console.log('Panels position changed:', args.changedPanels);
  console.log('User interaction:', args.isInteracted);
};

<DashboardLayoutComponent
  panels={panels}
  change={handleChange}
>
</DashboardLayoutComponent>

Key Features:

• Change event fires on any layout modification
• Access to added, removed, and repositioned panels
• User interaction detection
• See events-reference.md for drag, resize, and other event handlers
