Drop Down Menus in SharePoint Online

Question

I am trying to enable Drop Down Menus in SharePoint Online by enabling structural navigation as described here

However the top link bar Site items do not display any subsites as dropdowns? Am I missing something?

Answer 1

It would be nice, if you tried to understand how this structure behaves.

This is complex, try go step by step:

1. Site collection or Root Site:

   Site Setting -> Navigation -> Check Structural Navigation -> Check Show Subsites -> and click button OK.
   

2. Sub site of site collection(or root site):

   Site Setting -> Navigation -> Check Display the same navigation items as the parent site -> Check Show subsites -> and click button OK.
   

3. childs of subsite of Site Collection:

   Site Setting -> Navigation -> Check Display the same navigation items as the parent site -> Check Show subsites -> and click button OK.
   

4. Childs Recursive All

   Site Setting -> Navigation -> Check Display the same navigation items as the parent site -> Check Show subsites -> and click button OK.
   

See example of result:

Hope this help.
