I have a lightning:tree component in my application. I can react to its onselect event but how can I mark a specific tree node a selected from the my component controller?

    The way I see it, selected node will have a different class (like active) associated with it. You can add the class to selected node yourself in render-er.

  • I'm just a beginner with lighting components and never used renderer. Could you please share a link?
