# Menu waiting to hide himself

I discussed earlier why I prefer to hide my navigation menu. I finally decided to hide it only after a short time. Just the time needed for a user to see it. But how make it disappear only when it is not used for some time?

Here is how to accomplish that easily.

HTML:

        <div id="menuButton"></div>
        <div id="entete">
            <ul>
                <li> menu item 1 </li>
                ...
                <li> menu item n </li>
            </ul>
        </div>

CSS:

        #entete {
          top: 1em;
          left: 0;
          position: fixed;
          width: 10em;
          z-index: 2000; }

        #entete {
          top: 1em;
          height: 22em;
          left: 0;
          position: fixed;
          width: 10em; }

Javascript:

    var last=0;

    // will hide the menu in 5 seconds
    // if the variable 'last' has not changed its value
    function autoHideMenu(value) {
        setTimeout(function(){
            if ( last == value ) { hideMenu(); }
        },5000);
    }

    $(document).ready( function() {
        // show the menu when the mouse is on
        // the good area
        $('#menuButton').hover(showMenu);

        // If the mouse is on the menu change the
        // value of 'last'
        // try to hide the menu when the mouse
        // go out off the menu.
        $('#entete').hover(
            function(){last+=1;},
            function(){autoHideMenu(last);} );
        autoHideMenu(0);
    });

    // show / hide menu functions details

    // move to the left
    function hideMenu() {
        $('#entete').animate({left:"-10em"}, 500 );
    }

    // move to right and will try to hide in 5 sec.
    function showMenu() {
        $('#entete').animate({left:"0em"}, 500 );
        last+=1;
        autoHideMenu(last);
    }

Simple and lightweight. No timer (almost), no memory leak, no Date…
