Welcome to the Tab System

This is the overview tab. Tabs automatically remember which tab you had selected when you refresh the page using localStorage.

Use the arrow keys to navigate between tabs, or click on them directly. The system is fully accessible with ARIA support.

Key Features

• State persistence (remembers active tab)
• Keyboard navigation (Arrow keys, Home, End)
• Multiple style variants (default, pills, boxed, minimal, vertical)
• Color themes
• Icons and badges support
• Deep linking with URL hashes
• Fully accessible (ARIA)
• Mobile optimized

วิธีใช้งาน

Add the following HTML structure to create tabs:

<div class="tab-container" data-tab-key="unique_key">
  <ul class="tab-nav">
    <li><button class="tab-button">Tab 1</button></li>
    <li><button class="tab-button">Tab 2</button></li>
  </ul>
  <div class="tab-content-area">
    <div class="tab-panel">Content 1</div>
    <div class="tab-panel">Content 2</div>
  </div>
</div>
