I'm over simplifying a little bit, but WordPress is applying current-menu-item to all menu items with identical objects that are connected to the page you are viewing. Which definitely makes sense in a way, because generally you want to identify the element you are viewing, not the menu item you clicked. So I hate to break it to you, but I'm pretty sure it is indeed working properly and as intended. Otherwise I would advice you to add detailed information.

@Nicolai Thank you so much for your time and help. I just want to get current menu id and if you want more detail then you can read this from here wordpress.stackexchange.com/questions/284986/…

I am in this problem for few days but not able to find out solution for this.

Are you working with taxonomies, pages? Or what are you referring to, when your speaking about terms?

I have four custom taxonomies and all these are assigned with lot of terms. I am using few of these terms in multiple places and i have three level menu. I have AND condition in my tax_query among menu item and its parent menus. I am getting menu id correctly with that code but when there are multiple occurrence of this term it always return id of first occurrence and it is because of current-menu-item class.

You're just getting the first id, because the code in your other question is breaking after the first occurrence.

Are those hierarchical taxonomies?

Thank you for your time and help. It is much appreciated.

So you're mixing the taxonomies in your menu?

Because I think having the same term name in different taxonomies shouldn't add the class.

Yes.

So you're using the same term of the same taxonomy on multiple instances?

But i have same term from same taxonomy with same url. But in my case these terms should bring different posts depending on its parent terms.

Yes you are right

Or the class current-menu-item added.

Anyhow, I got to go for now, good luck!

But i have different structure and my client requirements are strange. I can share a link for my site if you want to see?
