JCombobox, editor and rendering

Question

Like the JCombobox ListCellRenderer, I have a class similar to this:

class ZComboBoxRenderer extends JPanel implements ListCellRenderer{
private ZGrid grid;
public ZComboBoxRenderer(ZGrid grid) {
    setLayout(new BorderLayout());
    this.grid = grid;
    add(new JScrollPane(grid), BorderLayout.CENTER);
}
public ZGrid getGrid(){
    return grid;
}
@Override
public Component getListCellRendererComponent(JList list, Object value,
        int index, boolean isSelected, boolean cellHasFocus) {
    grid.fetchSQL();
    return this;
}
}

ZGridhere continues JTable.

Like a ListCellRendererComponent, I provide the JPanel that has ZGridinside, before JCombobox. The problem is that in her list this ZGrid is drawn correctly. But it is also painted inside the JCombobox editor. I uploaded an image to show it better.

Is there a way to separate the editor from the list?
