@armandkeller You need to pass the forwardedRef property to GroupPanel.Container:

...
containerComponent={({ children, forwardedRef }) => (
    <GroupingPanel.Container
          style={{ width: "auto", marginRight: "10px" }}
          children={children}
          forwardedRef={forwardedRef}
    />
)}
...

Unfortunately, this property is not included in the documentation. We will add it in the near future.
