+## Ejemplo
+
+```tsx
+<Accordion defaultValue="section-1">
+  <AccordionItem value="section-1">
+    <AccordionTrigger>Seccion 1</AccordionTrigger>
+    <AccordionContent>
+      Contenido de la primera seccion.
+    </AccordionContent>
+  </AccordionItem>
+  <AccordionItem value="section-2">
+    <AccordionTrigger>Seccion 2</AccordionTrigger>
+    <AccordionContent>
+      Contenido de la segunda seccion.
+    </AccordionContent>
+  </AccordionItem>
+</Accordion>
+```
+
+## Notas
+
+Usa Mantine Accordion nativo. Soporta type single (default) y multiple para multiples items abiertos. El chevron se maneja automaticamente por Mantine. AccordionItem requiere prop value unico. Exports: Accordion, AccordionItem, AccordionTrigger, AccordionContent.
