I populated the dropdown with the help of array. for example I have array with elements (ali,abid,naqvi).
when I clear the cache and reload the page. and first time I am unable to select first value which is "ali". but if after cache clear and page reload, I select "abid" or "naqvi" first time and then select "ali" it work fine.
in short...after page reload I cann't select first value of dropdown unless I select other values first.
