What is the name of the panel widget that slides from the top of the window?

Hello.
I am a beginner who just recently started learning GTK4.

I would like to know the name of the panel widget that slides into view when the information button in the header bar is pressed in this demo video(Scalable lists and grids)

Or is the source code for this demo available somewhere?

You can always use the GTK inspector to inspect any GTK application, select the widget and check the widget tree to see what the widget is and what hierarchy it resides in.

Thank you. I don’t know where to find this demo, so I looked up the structure of another similar application: ActionBar seems to be a similar widget, but it appears to be displayed from the bottom of the window.

But anyway, thanks for sharing your tips.
