This can be achieved within the Add Content to your hub screen.
Within our default NewsWall template, there are two types of menu structures.
You can add a simple section menu format or you can add sub sections also.
The link below will show you the difference between the two:
Sections vs Sub Sections
You will see that the first two links at the top (Newsroom & We are eBay) link directly to another page. These are what we refer to as Sections.
However, if you click on the third option, titled More, you will see a drop down menu will appear. The options within that drop down menu are what we refer to as Sub Sections.
To add a section to your hub, click on the blue arrow button next to the word Menu.
If you would like to add a sub section, click on one of the sections you added and you will see dark grey plus icon.
If you click on that icon, it will add a sub section to your standard section.
Sections and Sub Sections can have their order arranged by clicking on the “grippy” icon (dots icons) located at the left-hand side of each Section/Sub Section.
