How to get div to automatically scroll down when height increases?

I have an autocomplete. When the dropdown appears, it may go out of view because it is close to the bottom.
The height of the div that contains this dropdown is increases. However, it does not automatically scroll to the end.
How to get it to scroll to the end?

Scrolling to a target after a div is hidden

I have a page of divs that display thumbnail images. Each is set so that when it's clicked on, a larger version appears in a larger pair of divs, centered in the window. One is a frame, the inner div is the image. Those divs are initially hidden and become visible via a javascript:
document.getElementById('frame').style.visibility="visible".
document.getElementById('print').style.visibility="visible".
They're sized and centered just right by the javascript but in the background it scrolls to the top of the page of thumbnails, so when closed, the user has to scroll down the page again to get back to where they were.
I've tried inserting the two divs in every conceivable place of the page, inside and outside the main page divs, top and bottom of the page... I've also tried relative, absolute and even sticky positioning without luck.
So I pursued scrolling the page when the divs are closed (hidden again) but that too is failing whether I use anchors or scrolling. In the script below, if the the alert is active, it shows the page scrolled to the correct position in the background. As soon as the alert is closed, it jumps back to the top of the page. 'pid' is the id of the targeted thumbnail.
function hideprint() {
document.getElementById('print').style.visibility="hidden";
document.getElementById('frame').style.visibility="hidden";
document.getElementById(pid).scrollIntoView();
// alert(pid);
}
I've also tried 'display' instead of 'visibility' with the same results.
How can I display these divs then get the page to stay or return to where it's been scrolled to when they're closed?

How to move to next page when reach the end of text?

I was trying to achieve this concept that the designer required me to do but unfortunately, I haven't had luck doing the exact thing.
What I want to achieve is when the user scrolls and detect the end of its text it will move to another page or div.
Each div has fixed height so the text that overflows with the div should be scrolling.
Example

jQuery - Show and Hide when element is 190px from the bottom of screen?

So I need an offsetBottom() jQuery function essentially. I have a fixed div that overlays the entire website, but I also have a div at the bottom of each page which contains the exact same content. My goal is to get the fixed overlay to disappear once the TOP of the div at the bottom of the page becomes visible, or is at the same height from the bottom as the overlay, even when the page is resized, then the overlay re-appears when the top of the div goes below the fixed div.
I am sorry I have no code example, I have been trying to use offsetTop() but the pages are of varying heights and it will only show/hide when the div reaches the very top of the web browser.

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.
