Buenas tardes a tod@s;
Estoy intentando modificar el bloque "Course Overview" de Moodle 2.8.3 a partir del código modificado de otro bloque. La idea es que Course Overview, muestre también la categoría del curso dónde está alojado este, como lo hace el otro bloque.
He intentado copiar el código del curso que sí realiza esta acción, pero sin éxito ya que no funciona correctamente.
Otra solución, sería añadir el bloque que sí muestra las categorías, en vez del "Coure Overview" pero... No funciona del todo correcto, por el JS. Seguramente sea un problema de compatibilidad, no lo tengo claro.
