How to use Vue three-layer nested routing

This time I will show you how to use Vue three-layer nested routing, and what are the precautions when using Vue three-layer nested routing. The following is a practical case, let's take a look.

Vue nested routing:

Achieve the effect (the routing is nested at three levels, click on the first-level tab to display the second-level tab effect, click on the second-level tab to switch the corresponding content, Content not in the tab area will not be rendered repeatedly when switching):
