Common use of v-if in Vue

Small partners who have used Vue must have used the V-if attribute, but this property is mainly for what it is, and he has to use those.

Here I sum up,v-if use generally has two scenes : 1-Multiple elements show or hide an element by conditional judgment. or multiple element 2-Toggles between two views

I've written two examples below, a simple example of the official Vue. The first instance implements the display of the type equals a different value, a,b,c three elements. The second example is implemented, click the button to implement the two views of the switch.
