Group controls

Header action components let you render your own controls (buttons, menus, or status indicators) into the left, right, and prefix regions of a group's header bar. Use them to add per-group actions such as split, close, or a context menu.

Hiding the header

Instead of customising the header, you can hide it entirely through the hidden property on panel.group.header:

panel.group.header.hidden = true;
