Minimal mistake - custom sidebar navigation menu

I managed to create the custom sidebar navigation menu. but one problem left.

It seems navigation menu highlights the current page.

But my case, It doesn’t.
How do I configure sidebar navigation menu to highlight the title of current page?

You don’t have to do anything special. The sidebar is checking if page.url matches the URL specified in your sidebar nav. If they match it gets the active class which bolds the title.

Without seeing your source code, I’m guessing they don’t match.

You are the best!!
