How to correctly highlight the current navigation in template inheritance? (Waiting online...)

Similar to the navigation above, I used the principle of template inheritance to define a base.html file in thinkphp, which contains the general header, nav navigation, and footer bottom. Other html files will inherit this base.html template.

• How can I highlight the navigation corresponding to the current page when visiting other pages?

• As shown in the picture above, when I visit the actual page, how can I highlight the navigation corresponding to the current page, if the navigation is a multi-level navigation?

• When I visit the sub-navigation corresponding to the main navigation, how can I correctly highlight the main navigation on the sub-navigation of the corresponding page?

Waiting online, I hope all my friends can help me with my doubts.
