Docking Frames default tabs horizontal alignment

I’m using DockingFrames library to create a tabbed interface where on startup the user sees an empty working panel and clicking a series of icons he can decide what tabs to open and show.

Right now by dropping the Dockables to a SplitDockStation with a SplitDockProperty they work as intended

station.drop(red, center);
station.drop(green, center);
station.drop(blue, center);```

however I don't want all tabs to be opened on startup, I want them to be opened when the user clicks the icon to activate one.
I tried using the above to drop them and then

station.removeAll();

to remove them however that removes also their default position and when I click the icon to activate more than one panel they all show vertically stacked.

How can I let them be shown one beside the other?

The documentation is not clear to me as I spent hours trying to figure out how. Below the example I am working on:

```import bibliothek.extension.gui.dock.theme.EclipseTheme;
import java.awt.Color;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;

import javax.swing.JCheckBoxMenuItem;
import javax.swing.JMenu;
import javax.swing.JMenuBar;
import javax.swing.JMenuItem;

import bibliothek.gui.DockController;
import bibliothek.gui.DockFrontend;
import bibliothek.gui.Dockable;
import bibliothek.gui.dock.DefaultDockable;
import bibliothek.gui.dock.SplitDockStation;
import bibliothek.gui.dock.event.DockFrontendAdapter;
import javax.swing.JFrame;
import javax.swing.JPanel;

public class DockFrontendExample
{
    public static void main(String[] args)
    {
        JFrame frame = new JFrame();
        DockController.disableCoreWarning();
        DockFrontend frontend = new DockFrontend(frame);
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

        EclipseTheme theme = new EclipseTheme();
        frontend.getController().setTheme(theme);

        SplitDockStation station = new SplitDockStation();
        frame.add(station);
        frontend.addRoot("split", station);

        /* Let's create some Dockables */
        Dockable red = createDockable("Red", Color.RED);
        Dockable green = createDockable("Green", Color.GREEN);
        Dockable blue = createDockable("Blue", Color.BLUE);

        frontend.addDockable("red", red);
        frontend.addDockable("green", green);
        frontend.addDockable("blue", blue);

        /*
        SplitDockProperty center = new SplitDockProperty(0, 0, 1, 1);
        station.drop(red, center);
        station.drop(green, center);
        station.drop(blue, center);
        */

        frontend.setShowHideAction(true);

        JMenu menu = new JMenu("Panels");
        menu.add(createMenuItem(red, frontend));
        menu.add(createMenuItem(green, frontend));
        menu.add(createMenuItem(blue, frontend));
        JMenuBar menuBar = new JMenuBar();
        menuBar.add(menu);
        frame.setJMenuBar(menuBar);
        frame.setSize(900, 500);
        frame.setVisible(true);
    }

    private static Dockable createDockable(String title, Color color)
    {
        DefaultDockable dockable = new DefaultDockable();
        dockable.setTitleText(title);
        JPanel panel = new JPanel();
        panel.setOpaque(true);
        panel.setBackground(color);
        dockable.add(panel);
        return dockable;
    }

    private static JMenuItem createMenuItem(final Dockable observed, final DockFrontend frontend)
    {
        final JCheckBoxMenuItem item = new JCheckBoxMenuItem(observed.getTitleText());

        frontend.addFrontendListener(new DockFrontendAdapter()
        {
            @Override
            public void shown(DockFrontend frontend, Dockable dockable)
            {
                if (dockable == observed)
                {
                    item.setSelected(true);
                }
            }

            @Override
            public void hidden(DockFrontend fronend, Dockable dockable)
            {
                if (dockable == observed)
                {
                    item.setSelected(false);
                }
            }
        });

        item.addActionListener(new ActionListener()
        {
            public void actionPerformed(ActionEvent e)
            {
                if (item.isSelected())
                {
                    frontend.show(observed);
                }
                else
                {
                    frontend.hide(observed);
                }
            }
        });
        item.setSelected(frontend.isShown(observed));
        return item;
    }
}```

Ok I solved by using the Common instead of the Base library.

    control = new CControl(frame);
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    frame.add(control.getContentArea());

    CGrid grid = new CGrid(control);
    work = control.createWorkingArea("work");

    grid.add(1, 0, 1, 1, work);

    control.getContentArea().deploy(grid);
