Tengo un pequeño problema en el que mi menú desplegable no funciona con Bootstrap. El menú desplegable solo aparece en pantallas más pequeñas que la variable $md.
El problema es que cuando hago clic en el ícono desplegable, parece que no funciona. Tengo el código HTML a continuación, pero si desea ver el proyecto completo, eche un vistazo a este repositorio de Github.
