Import Vue Instance in Vuejs as well as the usage of Tabs component in VueJS

[mrchow19910319]

I got this error when I try to run my app... I'm not sure how to add component into default.vue though...

Sorry if this question is too basic.

ERROR [Vue warn]: Property or method "nav" 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.

Another thing I don't understand is that in Vue if you want to use Tabs as your navigation bar, then you have to include all the HTMLs inside the default.vue layout??? Or you can create different vue components and later import them into the default layout....
