First add some standard controls to your page.

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 the following markup to add CheckBoxes, a DropDownList, RadioButtons, a Button, and a TextBox to the main content of  your page.

   <ul>        
   

           <li>        
   

             <label>TextArea</label>
             <asp:TextBox runat="server" ID="TextBox3" TextMode="MultiLine"></asp:TextBox>        
   

           </li>
   

           <li>        
   

               <label>Dropdown with Optgroups</label>        
   

               <asp:DropDownList runat="server" ID="DropDownList2">
               <asp:ListItem Text="A"></asp:ListItem>
               <asp:ListItem Text="B"></asp:ListItem>
               <asp:ListItem Text="C"></asp:ListItem>

           </li>
   

           <li>
   

               <label>Radio</label>        
   

               <asp:RadioButton ID="RadioButton1" GroupName="radiobutton1" runat="server" Text="radio1" />

                 <asp:Button runat="server" ID="Button1" Text="Submit1" />        

             </li>        

     </ul>
