What component is this that Visual Studio uses?
Does anyone know what component this is? (The expanded option toolbox, where I can cl开发者_高级运维ick on it and it opens a lot of options, I can put in the left side of the form or the right.)
I don't think it's a treeview (or is it a customized treeview?).
If there isn't such component, how can I implement it?
I found what I wanted. Its using the WPF application, the component Expander, found on Controls tab.
