I saw that this feature has been added to the Road Map for 2020

Thank's to everyone at Telerik

I have the same request. It would be enough if there is some kind of container where I can place my own content. A good example is Microsoft Teams where there is a three-dot-button which opens a small container. I could place a menu, buttons or whatever I like inside this container. It helps organize navigation-items as "important" and "less important".

The attached sreenshot shows how MS is doing it in Teams (sorry, in German).

Hi Guys,

I also would like to have this feature

Hey Martin, 

Just to help this thing gain some traction, we are looking for this exact functionality right now as well. We're currently stuck attempting to roll our own by adding expanders to the ContentTemplate of the RadNavigationViewItem, but it isn't nearly as feature-rich or clean as what we would expect from a supported control.

What Olivier linked is exactly what we're looking for as well! Although we'd greatly appreciate just the submenu items for the time being and maybe update with additional functionality such as a context menu so that we can get our hands on the base functionality as soon as possible. 

Thanks!

Hello Martin,

We are looking for the same feature! We love the NavigationView but we need to be able to display subitems when a main menu entry is selected. Moreover we can directly go to the subitems by mouseover on a main menu entry (with a contextmenu-like).

I added a screenshot of the exact behavior we would like to implement (this example come from AzureDevOps plateform!).

Best regards,

I would also like to see this feature, preferably with full hierarchical support with multiple levels.

Another good example of how it could look is here. http://wrapbootstrap.com/preview/WB0573SK0

Thanks,

Richard
