좌(우)측 서브메뉴 다시 질문드려요! - 커뮤니티

그누에 있던 파일인데 적용하니 전체메뉴에 대한 서브메뉴들이 다 나오는데

어느부분을 수정하면 그룹을 클릭했을때 해당서브메뉴만 나올수 있는지 궁금합니다.

<script type="text/javascript">
<!--
    function display_submenu(num) {
         document.getElementById("mysub"+num).style.display="block";
    }
//-->

<style TYPE="text/css">
<!--

#mysubmenu .leftmenu_s {line-height:35px; margin-bottom:5px; padding-left:20px; background-color:#F2F5F9;border-bottom:1px solid gray;}
