How do I highlight the current navigation correctly in template inheritance? (online etc...) ）

Similar to the above navigation, I use the principle of its template inheritance in thinkphp to define a base.html file that contains the generic header header,nav navigation , footer bottom, Other HTML files will inherit the base.html template.

• How do I highlight the navigation of the current page when I visit other pages?

• For example, when I visit the actual combat page, how to highlight the current page corresponding navigation, if the navigation is multi-level navigation?

• How do I correctly highlight the main navigation on a sub-navigator of the corresponding page when I visit a subordinate navigation that corresponds to the primary flight?

Online, and so on, I hope that friends can guide the doubts.
