Vue route highlighted in two ways
1. The first use mui
if mui-active tab will be highlighted at this time the class each tab, if you do not write mui-active in this kind of thing, there is a default router-link-active class, we also need to own in this class to write highlight style, highlighted already have an existing class mui-active, so the solution is: to achieve in the route
The second way: determining path, if at this time in the home, the home path / msite, and determines the current path is not the same, if the same, then the highlight class guide-item effect.
: Class = "{on: ' / msite === $ route.path'}"
