Must be done in my project which has been used with visual web developer 2008 vb.
[url removed, login to view] must look and feel like the one on city search
[url removed, login to view] pop-out when a user clicks on the category which is a drop down list and once the user clicks on one of the categories a sub list pop-up with the sub categories. Then the user must click on a sub category or have an option to go back to the prior menu or to the main menu. Once they click on the sub-category the pop-up menu closes and the string is embedded into the drop down list.
Please see the attached project.
