I created a simple ListPanel inside a OverhangPanelSetScene, then created a LabelList child and populated it with some entries. The LabelList shows up fine, but the leftLabel and rightLabel above it do not.
I also tried to use showSectionLabels=true with sectioned content inside my LabelList, but since leftLabel is not showing up I can’t see the section titles either.
I ran the component example you posted above within the Scenegraph tutorial app, and I’m able to see both labels above the highlighted item in the listpanel.
Could you send a screenshot of what’s on your screen?
