OpenBOX Workspace handling

I'm in the process of customising Openbox and am trying to get Workspaces handled the way Xfce4 does it, but can't figure out how.

Xfce4 which has four workspaces (initially) on the top line and you can select each by clicking. You can also drag apps from one workspace to another.

How can I add this functionality to Openbox?
 
yes its the "Desktops" section, (sorry I m not running o/box now to check)
Desktops == workspaces on Openbox
 
The default shortcut to get to next workspacei is ctl+alt+right-arrow. Default to send an application to the next desktop is
shft+alt+right-arrow
Code:
<keybind key="S-A-Right">
    <action name="SendToDesktop"><to>right</to><wrap>no</wrap></action>
  </keybind>
