css:

/*simple dropdown box*/     .selectmenu{         font-family: arial, sans-serif, tahoma;         -webkit-appearance: none;  /*removes default chrome , safari style*/         -moz-appearance: none; /* removes default firefox style*/         background: white;         width: 80px; /*width of select dropdown give space arrow image*/         text-indent: 0.01px; /* removes default arrow firefox*/         text-overflow: "";  /*removes default arrow firefox*/ /*my custom style fonts*/         color: black;         border-radius: 2px;         padding: 5px;         border:0 !important;         box-shadow: inset 0 0 1px rgba(000,000,000, 0.5);         font-size: 1.2em;     }

javascript:

$(function() {     $('#select').change(function(){         if ($(this).val() == "3") {             $('#hidden_div').show();         } else {             $('#hidden_div').hide();         }     }); });

i tried code. working. maybe try alternatives. use .css() function of jquery change display none block , vice versa.

$(function() {     $('#select').change(function(){         if ($(this).val() == "3") {             $('#hidden_div').css('display','block');         } else {             $('#hidden_div').css('display','none');         }     }); });

here's screenshot prove works:

hope helps. goodluck!
