I have a drop down menu that contains a set of menu items. Each menu
item is planned to make ajax call to change the content of the page when
it's clicked. I used link_to_remote successfully to make the ajax call
and update the specific div
However, After clicking the menu item, the menu doesn't close, and it
remains open. The contents already changed in the background, but the
menu is still open, which hides a part of the page.
