[Vuejs]-Can we mount a Vue component to multiple div element?

I believe that what you are trying to do can be achieved by having a root component which can include your component as a child component.

If you need that one component will appear several times in the same page, this is the direction:

Base component:

import ChildComponent from './ChildComponent';

export default {
    components: {
        ChildComponent
    },

    :
    :

Then you can simply include it (<child-component/>) in any place you need.

Notice, that in this case the new parent component is the one you need to assign to your vueInstance in order to become the root.
