That is a web site, so you need to look at the options available within ASP.NET for creating drop down lists. There are lots of articles here on CodeProject that will offer suggestions.

I'm not sure Winforms or even WPF allows this kind of theming natively. What you'll need to do is write your own usercontrol that inherits from the standard combobox. I think this usercontrol will consist of several standard controls: - a textbox - a button (that resembles the down arrow) - an invisible panel, size: width = textbox, height = 0 (by default) You then load this panel with the items (via labels or textblocks) and on click of the button the panel grows in size (at the position right below the textbox). When a label/textblock was clicked, the panel is closed again andf the text put in the textbox. hope this helps. PS: Please avoid text speech and mind the spelling (even if you're not native English)

WPF provides better styling support for controls.

Some replies here have assumed you are describing "theming:" (even though you never used that word, yourself): where theming means you want to create a control from which you could create any number of different look-and-feel variations from the base control. Looking at your question: and the example on the web page you linked to: are you really asking how to create a custom-themed control, or are you just asking how to make a drop-down that looks and behaves exactly like the one on that web-page ? Please clarify exactly what "style" and "styling" mean to you here. best, Bill

using System.Collections.Generic;
using System.ComponentModel;
using System.Runtime.InteropServices;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;

namespace Combo
{

public class Combo //:IDisposable
{
    private System.Windows.Forms.ComboBox li = new System.Windows.Forms.ComboBox(); //object
   // public event EventHandler SelectedIndexChanged; //The event handler name must match the event name.
   // private object\[\] eventObject; //One object\[\] for each event (one event here).
    public void Addselect(Control FormName, string name, int top, int left, int width, int height, string Text)
    {
        li.Top = top;
        li.Left = left;
        li.Width = width;
        li.Height = height;
        li.Name = name;
        li.FlatStyle = FlatStyle.Flat;
        li.CreateGraphics();
        li.Text = Text;
        li.IntegralHeight = false;
        li.MaxDropDownItems = 5;
        li.DropDownStyle = ComboBoxStyle.DropDown;
        li.Size = new System.Drawing.Size(136, 81);
        li.BackColor = System.Drawing.Color.DarkGray;
       

        FormName.Controls.Add(li);

       // eventObject = new object\[\] { this, "SelectedIndexChanged" }; //This is the object that will pass with the event.
        //It must be in that format exactly.
     //   li.SelectedIndexChanged += new EventHandler(SelectedIndexChanged);

//

    }

// private void SelectedIndexChanged(object sender, EventArgs e)
// {
// if (SelectedIndexChanged != null) //You must test this.
// {
// SelectedIndexChanged(eventObject, null);
// }
// }

    public void Additems(string\[\] items)
    {
        li.Items.AddRange(items);
    }

    public bool Enabled
    {
        get { return li.Enabled; }
        set { li.Enabled = value; }
    }
    public bool Visible
    {
        get { return li.Visible; }
        set { li.Visible = value; }
    }


}

}
