I want to have a icon when clicked it should display signout, changepassword. How can I do that. Something similar like facebook where there is a inverted triangle whenclicked displays privacy setting.

<td>
     <asp:Label ID="Label_UsereName" runat="server" Text="Label"></asp:Label>
 </td>

this type menu can be made using jquery

You will need to look into some javascript code which will show/hide your options.

jQuery Toggle or jQuery Show would be a good place to start.
