Ejemplos de Uso

Configuración Básica

// Inicialización simple
const nav = new ModernNavigation('.modern-nav');

// Establecer enlace activo
nav.setActiveLink('/productos');

// Agregar nuevo elemento de menú
nav.addMenuItem({
  href: '/blog',
  text: 'Blog'
});

Integración con Router

// Actualizar navegación basada en la ruta
function updateNavigation(currentPath) {
  window.modernNav.setActiveLink(currentPath);
}

// Escuchar cambios de ruta
window.addEventListener('popstate', () => {
  updateNavigation(window.location.pathname);
});

Búsqueda Personalizada

window.addEventListener('navSearch', async (e) => {
  const query = e.detail.query;
  
  try {
    const results = await fetch(`/api/search?q=${encodeURIComponent(query)}`);
    const data = await results.json();
    
    // Mostrar resultados
    displaySearchResults(data);
  } catch (error) {
    console.error('Error en la búsqueda:', error);
  }
});
