How to show a block on click in the list?

Question

Vue.js

Is it possible to switch blocks by clicking on the list using v-for in the list and storing the name in an array? Without the use of components using v-show.
Here is an example:

It is necessary that when you click in the list on the right, a certain block is shown. I'm showing everything at once :D

If you write data to an array, it will be even easier and more convenient.
