  • jQuery Lavalamp Effect

    Right, after several fruitless hours I figured I would trouble the kind people of GDF for their thoughts - I basically want a coloured border on the left of the currently active page <LI>, and I want this to smoothly follow the mouse up and down the <UL>. Trouble comes when I want to embed a <UL> in an <LI> element for a sub menu... turns out, things break

    I have tried simply using a class to denote the submenu items, rather than another <UL>, but then I cannot specify a different rollover effect for those <LI>s.

    Oh, and the current page/subpage should kinda be highlighted too lol.

    My HTML/CSS at the moment is:
    Code:
    div#menubox { padding:34px 0px; background:#2d2d2d; }
    div#menubox ul#menu { list-style:none; position:relative; }
    div#menubox ul#menu li { font-size:10px; padding:0px 0px 0px 30px; width:190px; }
    div#menubox ul#menu li a { position:relative; z-index:10; color:#878787; display:block; height:16px; padding:1px 0px; }
    div#menubox ul#menu li ul#submenu { list-style:none; position:relative; margin-left:-30px; }
    div#menubox ul#menu li ul#submenu li { font-size:10px; padding:0px 0px 0px 45px; width:170px; }
    div#menubox ul#menu li ul#submenu li a { position:relative; z-index:20; color:#6daee1; display:block; height:16px; padding:1px 0px; }
    
    div#menubox ul#menu a.current { margin:0px 0px 0px -30px; padding:1px 0px 1px 6px; width:214px; border-left:25px solid #000000; background:url('sh/im/page_arrow.png') center right no-repeat; }
    div#menubox ul#menu ul#submenu a.current { margin:0px 0px 0px -45px; padding:1px 0px 1px 6px; width:199px; border-left:40px solid #6daee1; }
    div#menubox ul#menu div.ahover { position:absolute; z-index:5; border-left:25px solid #000000; background:url('sh/im/page_arrow.png') center right no-repeat; margin-left:12px; }
    div#menubox ul#menu ul#submenu div.ahover { position:absolute; z-index:15; border-left:40px solid #6daee1; }

    <div id="menubox">
        <ul id="menu">
            <li><a href="#">Welcome</a></li>

                    <li><a href="#" class="current">Company Structure</a></li>
                    <li><a href="#">Mission, Vision &amp; Values</a></li>
                    <li><a href="#">Financials</a></li>
                    <li><a href="#">Careers &amp; Vacancies</a></li>
                    <li><a href="#">Location</a></li>
                </ul>
            </li>
            <li><a href="#">Contact</a></li>
            <li><a href="#">News</a></li>
        </ul>
    </div>
    I have tried both lavalamp and ahover plugins, are there any others available? Or any ideas for how to achieve this? Other than a plain-jane CSS rollover of course; that's no fun

    The only way your going to be able to achieve that effect is using javascript or flash. I would recommend looking into JQuery or YUI. You might even get lucky and find a similar effect that has already been developed using those libraries. Otherwise your going to need to get your hands a little dirty in the wonderful world of javascript programming. I haven't developed anything similar although if I had I would gladly share the code. YUI has very powerful animation library that would be perfect for this type of thing.

      http://apycom.com/ seem to have figured it out. Would love to know exactly how they didnt without having to pay them.... At quick glance it seems to be in the CSS by using compound selectors.

        Thank you for answering my questions. The project that I'm working on is about how math is used in almost every profession, so each student has to pick a job and then research how math is used in that...

        What kind of simple math do you use on a regular basis whilst doing your job?

        In my area of the country, there are an abundance of this.

        Believe me, despite over 12 years of agency experience and 15 years being a ''freelancer'', even I have encountered this bias. Especially...

        I wouldn't say it means nothing. If it's coupled with all the other things, like internships, actual employment and education, it definitely counts for something.
