Tudo funcionou bem, ate' eu colocar o v-for no li. O menu nao aparece aqui na pagina. E no console tem o erro.
[Vue warn]: Property or method "routes" is not defined on the instance but referenced during render. Make sure that this property is reactive, either in the data option, or for class-based components, by initializing the property. See: https://vuejs.org/v2/guide/reactivity.html#Declaring-Reactive-Properties.
