Las tiendas online, los mercados, los sitios web inmobiliarios y los grandes blogs suelen tener una cosa en común: muchos datos a los que el usuario puede acceder. Trabajar con grandes conjuntos de datos puede resultar rápidamente desalentador y abrumador. Los filtros permiten a los usuarios acotar los resultados, haciendo que encontrar lo que buscan sea más fácil. Al mismo tiempo, también pueden aumentar la complejidad de tu interfaz. Cuando crees un formulario de filtro, es crucial que sea lo más sencillo posible para que los usuarios puedan aplicar sus ajustes de forma rápida y eficaz. Independientemente de cómo accedan los usuarios a la web, siempre deben saber qué filtros están activos y si se han aplicado.

Solución
Permite a los usuarios filtrar los resultados irrelevantes. El Ejemplo 10-1 muestra un filtro ejemplar en HTML.
