With ReactJS i am using MDBNav from MDBreact.
This is the code od the container where is props.data defined:
import React from \'react\' import
You need to specify the active option, not activo:
active
activo
{a.nombre}
By doing {a.active} you just add true to MDBNavLink (which doesn't make sense), you need to add active={true} instead
true
active={true}
