How to make my child hub sites to inherit navigation from top level sites?

I have the very same Issue.

Site MYSITE is a Communication Site registered as a Hub.

Site YOURSITE is a Communication Site associated to the Hub MYSITE.

MYSITE has a Top Navigation and I want YOURSITE to inherit that Navigation. It's simply not working.

Why is Microsoft telling everybody to "not use sites and subsites, use a flat structure with Hub sites instead" when that is not working and the options for navigation inheritance is still configurable for subsites but also not working. Really, what are we even paying for?

Dear Aditya Biswas,

Thank you for posting your query in our community.

I understand your concern and to my knowledge, child sites and Parent hub associations will not be inherited from the partner’s site. Only the sites that are associated with the patent site will inherit the parents’ site.

As a example

• Parent hub (level 1): Think of associated hubs on level 1 as "Parent" hubs that determine the search scope for peer associated hubs.
• Associated child hub (level 2): These hub sites are already associated to the parent hub and content within these sites appear when users search at any of these hubs.
• Associated child hub (level 3): This level (and all preceding levels) of peer associated hubs behaves the same way as the first level. Content on sites beyond level 3 won't appear in search results.

We crate a parent site called “Microsoft” and also we crate a site called “kasun 1” we make this site Parent hub association with the Microsoft site navigation from the Microsoft site will not appear in the kasun1 site. This is expected behavior by the SharePoint development.

• If you want to inherit navigation from “ Microsoft site” you have to crate a association with the hub and select the parents site.

Select the site >>> if site registered as a hub please unregister it >> associate this site with a hub>> select the parents site .

for more information please refer to this article Associate a SharePoint hub site to another hub to connect search experiences

Appreciate your patience and understanding. Have a great day!

Dear Aditya Biswas,

Thank you for posting your query in our community.

To have better insights of the problem, could you please go to the SharePoint admin center, get the "Hub" column, find the 3 sites, and share screenshots of the 3 sites linking relationship?

At the same time, could you please also provide the URLs of the 3 sites? Kindly hide your domain part in URLs for privacy protection.

More further, please let me know how did you edit the navigation on the top site. If you can provide a screenshot of the navigation editing location, that would be much appreciated.

Appreciate your patience and understanding. Have a great day!

Yours sincerely,

Hey Sophia,

So, in my SharePoint, the Main Portal and the Departments sites are both hub sites.

Here, the Departments site is associated with the Main Portal.

My understanding is that all the sites associated with the parent hub association inherits the navigation bar menu from the parent hub.

What my question is that, if the Departments site is associated with the Main Portal, why is it not inheriting the navigation bar menu from the Main Portal?

Dear Aditya Biswas,

Thank you for posting your query in our community.

There might be some misunderstanding here. After a site is registered as a "Hub site", other sites can be linked to it but there is no 2nd level or 3rd level child hub sites as "hub sites" doesn't allow being linked to a different "hub site".

From your description, I guess the 3 levels you are referring to are hub sites, site collections linked to hub and subsites, like below pictures. Kindly let me know if my understanding is correct.

If my understanding is right, may I confirm if you updated the navigation from top bar of the hub site?

After it is added, it should appear in sites connected to it and subsites immediately.

Appreciate your patience and understanding. Have a great day!

Yours sincerely,
