<h2>Key Features:</h2>

|
|
<ul>
|
|
|
<li>
|
|

|
|
<code>vpi-chevron-right</code> icon instead of CSS triangle
|
|
|
</li>
|
|
|
<li>
|
|
|
✅ <strong>Correct rotation:</strong> Default 90° (pointing down),
|
|
|
opens to 0° (pointing right)
|
|
|
</li>
|
|
|
<li>
|
|
|
✅ <strong>No JavaScript:</strong> Pure CSS rotation with
|
|
|
<code>transform: rotate()</code>
|
|
|
</li>
|
|
|
<li>
|
|
|
✅ <strong>Smooth transitions:</strong> CSS transitions for rotation
|
|
|
and color changes
|
|
|
</li>
|
|
|
<li>✅ <strong>Hover effects:</strong> Icon color changes on hover</li>
|
|
|
<li>
|
|
|
✅ <strong>Conditional rendering:</strong> Only items with children
|
|
|
show the caret
|
|
|
</li>
|
|
|
<li>
|
|
|
✅ <strong>Accessibility:</strong> Native details/summary keyboard
|
|
|
navigation
|
|
|
</li>
|
|
|
</ul>

<h2>Updated Implementation:</h2>

<h2>Icon Rotation Behavior:</h2>
|
|
|
<p>
|
|
|
<strong>Default state (closed):</strong> Icon rotated 90° (pointing down
|
|
|
like ∨)
|
|
|
</p>
|
|
|
<p>
|
|
|
<strong>Open state:</strong> Icon rotated 0° (pointing right like >)
|
|
|
</p>
|
|
|
<p>
|
|
|
This matches the expected behavior where the caret points down when
|
|
|
collapsed and right when expanded.
|
|
|
</p>
|
|
|
</div>
|
|
|
|
|

<strong>Try it:</strong> Click on the sections with carets to see the
|
|
|
smooth rotation animation!
