Adjust import paths

Ensure your @/lib/utils or equivalent classname helper is correctly imported.

import {
  McAccordion,
  McAccordionContent,

} from '@/components/ui/mc-accordion';

      <McAccordionItem value="product">
        <McAccordionTrigger>Product Information</McAccordionTrigger>
        <McAccordionContent>
          <p>Our flagship product combines cutting-edge technology with sleek design.</p>
        </McAccordionContent>
      </McAccordionItem>
    </McAccordion>
  );
}

Examples

Basic Accordion

<McAccordion defaultValue={['product']} className="w-full max-w-[503px]">
  <McAccordionItem value="product">
    <McAccordionTrigger>Product Information</McAccordionTrigger>
    <McAccordionContent>
      <p>Our flagship product combines cutting-edge technology with sleek design.</p>
      <p>Key features include advanced processing capabilities and an intuitive interface.</p>
    </McAccordionContent>
  </McAccordionItem>

  <McAccordionItem value="shipping">
    <McAccordionTrigger>Shipping Details</McAccordionTrigger>
    <McAccordionContent>
      <p>We offer standard, express, and overnight shipping.</p>
      <p>Free international shipping is available over the minimum order amount.</p>
    </McAccordionContent>
  </McAccordionItem>

  <McAccordionItem value="returns">
    <McAccordionTrigger>Return Policy</McAccordionTrigger>
    <McAccordionContent>
      <p>Returns are accepted within 30 days when items are unused and in original packaging.</p>
    </McAccordionContent>
  </McAccordionItem>
</McAccordion>

Width Control

The accordion already accepts className, so width is usually controlled from the parent with Tailwind utilities.

<McAccordion className="w-full max-w-[503px]">...</McAccordion>

Use w-[503px] for a fixed width, or w-full max-w-[503px] for a responsive layout that keeps the default width as a maximum.

Long Trigger Text

When trigger labels are long, keep the chevron separated from the text so content wraps cleanly instead of sliding underneath the icon.

<McAccordionItem value="faq">
  <McAccordionTrigger>
    What happens if my accordion title is much longer than a single line?
  </McAccordionTrigger>
  <McAccordionContent>
    <p>The trigger text should wrap naturally while the chevron keeps its own space.</p>
  </McAccordionContent>
</McAccordionItem>

Multiple Paragraphs

McAccordionContent works well with stacked content such as paragraphs, links, and lists.

<McAccordionContent>
  <p>First paragraph of supporting information.</p>
  <p>Second paragraph with more details.</p>
  <a href="#learn-more">Learn more</a>
</McAccordionContent>
