I currently have 3 DropDownList's (ddl's) which all show up when the page loads. (ddl1: schools, ddl2:states, ddl3: citys). I want only only ddl1 to show up when the page loads, then when the user makes a selection, ddl2 will show up, then ddl3 when the user selects a state.
Ideas on how to do this would be great. Also I can foresee a problem, my current ddl's currently show (or select by default) the first item in the ddl. How do I make this so the default in the ddl is blank or no selection?
Thanks
