The WijSplitter control allows you to change the orientation of a splitter. Simply set the Orientation property to take advantage of this feature.

1. Create an ASP.NET Web application with a ScriptManager control and install Juice UI and the Wijmo Juice libraries to your project via NuGet.
2. Add a standard Panel control to the main content of  your page.        
3. Add a second Panel control within the first panel, Panel1.        
4. Add markup within each panel so the final markup looks like this:        

   <asp:Panel runat="server" ID="Panel1">        
   

               <div>        
   

                     panel1             
   

               </div>
   

               <div>
   

                     <asp:Panel runat="server" ID="Panel2">
   

                           <div>
   

                                 panel2</div>
   

                           <div>
   

                                 panel3</div>
   

                     </asp:Panel>
   

               </div>
   

   </asp:Panel>
   

5. While still in Source view, use the following markup to add a WijSplitter control to the page and set the TargetControlID to Panel1.

   <cc1:WijSplitter ID="Panel1_WijSplitter" runat="server"        
   

           TargetControlID="Panel1">
   

   </cc1:WijSplitter>
   

6. Use the following markup to add a second WijSplitter control to the page and set the TargetControlID to Panel2.

   <cc1:WijSplitter ID="Panel2_WijSplitter" runat="server"       
   

           TargetControlID="Panel2">       
   

   </cc1:WijSplitter>
