Dropdown list

Question

I want people to choose from a dropdown list,and their choice takes them to a page they have chosen.

Answer 1

In aspx

<asp:DropDown ID="MyDropDown" runat="server" AutoPostBack="true" OnSelectedIndexChanged="RedirectUser">
   <asp:ListItem Value="/MyPage.aspx" Text="MyPage"/>
</asp:DropDown>

In code behind

protected void RedirectUser(object sender, EventArgs e)
{
   Response.Redirect(MyDropDown.SelectedValue);
}

Okay read the "question" again and you didn't specify ASP.NET but nevermind, more details in the question would have helped

Answer 2

You can use something like this with a bit of javascript:

<select name='jumpMenu' onchange='javascript:window.location.href = this.value;'>
  <option value='Department.aspx?DeptID=0'>--Department 0</option>
  <option value='Department.aspx?DeptID=1'>--Department 1</option>
  <option value='Department.aspx?DeptID=2'>--Department 2</option>
  <option value='Department.aspx?DeptID=3'>--Department 3</option>
</select>
