We have a SharePoint site within a site collection. That site has a couple of items in the left navigation, e.g.
* Projects * Employees * Tasks
Is there a way, that if I click on
Projects, the navigation expands so that there is a subnav like this:
* Projects - Project A - Project B - Project C * Employees * Tasks
If yes? How can I do that? Can I do that only by using the Frontend? Or do I have to use something like the SharePoint Designer?
