i want to show only parent item. when i click on parent then it's child automatically open. 

Is there is any module for this. Or their is any other way to achieve this

Have you tried Dhtml Menu?


  Ordinarily in Drupal, in order to see the sub-items in a menu, you
  need to click the link of this item and wait for a full page load.
  After enabling DHTML Menu, clicking a menu link once will expand it to
  reveal its sub-items without reloading the page. A double-click on the
  item will load the page normally. Additionally, a cookie stores which
  menus are open and which are closed, so that the state of the menus
  remain consistent as you navigate around the site.
