HTML Horizontal Menu that Moves on Button Click

I need to create a horizontal menu that shows all of the possible items given the browser size, the rest of the items are hidden (they do not wrap to the next line). Then there is an arrow button on the far right side of the div, which when clicked, shows the next row of items. How can I do this? I'm not asking for anyone to write the code for me, I just need some direction. Are there any examples online of this? I don't want the arrow button to move the items slowly across the screen. I need it to just "jump" to the next row.
For example if the list of items is made up of three, each li element is 100px long and the total page with is 200px, one of the elements will be hidden. Once the button is clicked the first two items disappear and the last item displays.

There are many ways to do this, you can make the ul position:relative, then the li position: absolute, when clicked, change the positon of lis to show them.

As Ji Guang said. There are many ways of doing this. All that matters is that how you would like to implement it, or better said how the rest of your project is implemented.
For the menu as Ji Guang said, you can create a horizontal style list (maybe use float left on li for that). The ul must be now declared as relative and fixed height or width with overflow hidden, or better off fix the height as much you want and set width relative to the page. For the arrow to go throw the rest of the rows what I guess you want is some type of carousel. Now there are plenty of good plugins available online for that. Or you can always have it done yourself. If you are planning to do it yourself then you need to follow Ji Guang advice. Put the menu ul inside another div and then play with ul's positioning.

How can I map a horizontal scrollbar to a div within the page?

Let's say I have two divs on a page like this:
<div style="width:300px;height:100px;overflow:hidden">
<div style="width:3000px;height:100px">
some content
</div>
</div>
and let's assume that the outer div is positioned somewhere in the middle of the page.
Is there a possibility to "map" the global document scrollbar to that div so it's possible to use the mouse's / trackpad's horizontal scrolling feature to move that inner div to left and right?
I hope it's clear what I am trying to do...

I'm not sure it's possible to re-map the scrollbar's effected area. However, you might be able to achieve the same visual effect by making a fixed position div (position:fixed;), and keeping it on top of the one that needs to scroll left and right. You'd have to make the two divs siblings instead of parent>child, which hopefully isn't a deal-breaker.
This way, the page's scrollbar would effect the 'child' div just as it normally would, while allowing the other one to remain locked in place.
Hope this helps

Tool Tip jQuery to appear outside slide element

I have a jQuery conundrum that I'm not sure can be resolved. Inside a content slider I have absolutely positioned divs creating a tool-tip style pop-up on hover. Because the containing content slider overflow must be set to hidden, the tool-tip pop-up gets cut off where it overflows. I would like the pop-up to display in full when overlapping the slider it is contained within. If anyone has a workaround for this I'd be very appreciative!
Here's a link to my working file from which you can see the problem and the code.
Many thanks for any advice.

Your animation inside 'slidesContainer' relies on overflow:hidden so the large image doesn't stick out of the div and the only way for you to get the balloons pop out is to remove that overflow:hidden and make it visible
I don't think you can have the two at the same time

Right, so I don't think there was a straight forward solution so what I did was change the script to refer to div IDs instead of referring to the 'next' div. I moved the pop-up div's outside the slide element and absolutely positioned them relative to the page rather than the link. It's more long winded but works fine! Just means you need to refer individually to each pop-up div in the script. Thanks for you help anyway!

CSS Show active element above the div with overflow:hidden

I have a scrolling pane div with overflow:hidden. Please check it here. There are products as images with captions shown in the scrolling pane. When I move mouse cursor over a product div, it gets light-yellow background and changes its height - I just add a class to the div using jQuery and it works fine. The problem I need to solve some way is to show the expanded div for the active product as a separate div that appears above the scrolling pane, though now it appears inside that pane and extends it in its height. I want to make it look in similar way to this one. Here you move mouse cursor over the product and get an extended div showing you details. Surely, my task is a little harder because of that scrolling pane.

Shouldn't be too difficult if you use the .offset() method on hover of a .product. What you can do is the following:
In your .product hover event handler, get the offset of the product. This will give you the position of your product in relation to the document.
Next create your overlay product information div and append it directly to the <body>.
Set the overlay div to position: absolute and use the values returned from the offset call to position it.
Lastly make sure your overlay has a higher z-index than the scrolling pane and you should be in business.

Make a div fall off the page

So I have been playing with jQuery for a good time now and I'm trying to get an effect to work properly. I have a main square div in the middle of the page and when someone clicks a link I want the box to look like its falling off the page and disappear, revealing a new page behind it. I'v been playing with the easing plugin but I can seem to get what I want to work. Basically I have the div's top margin or just top distance increased to a large number. However, this just makes the div fall but it also expands my page and its just much lower on the page. I basically want the div to fall out of site and not change the dimensions of the site. Anyone know how to do that?
Thanks!

To prevent your page from redimensionning upon clicking on your link, add overflow:hidden to your div container 's css properties.
also, make sure you hide the div when the animation ends.
$('a').click(function(){
$('#thediv').parent().css('overflow','hidden');
$('#thediv').animate({'top': '+=500px', opacity: 0},function(){
$(this).hide();
});
});
