Floating element with table while you scroll

**bluespotjaw** · 11-10-2009, 09:22 AM

I'm looking for a code that allows me to have a table on the right side of the screen that and the image that I have in that table will move down as the screen scrolls down.

An example can be found on dotster's site when you search for a domain. When it gives you the results, make your browser window smaller and scroll down. You'll see under selected domains it moves as you scroll.

https://secure.dotster.com/dds4/inde...=test-test&tld[]=com&x=0&y=0

There's a code here on DD that is close:

http://www.dynamicdrive.com/dynamici...staticmenu.htm

This is only relative to the screen and I need one that is relative within a table on my site.

Anyone know where I can find this code or have one that I can use?

Thanks!

MJH, another great example but again it referenced the edge of the browser window and it ends up being in different spots depending on my window size and resolution.

No. It doesn't. The code works fine onresize, in both FF and IE.
YOUR problem is that you are using a table for page layout, instead of CSS.

**bluespotjaw** · 11-11-2009, 08:03 PM

vwphillips, I tried using the code but I couldn't get it to work on my page. The div p code was positioning it based on the edge of the window. This didn't work because my site is centered within a fixed table and it would look different to people with not maximized screens and different resolutions. I even tried taking out the div p tag and using just the float but it didn't work.

Now maybe I'm just messing it up.

Here's what I'd like. On my site page: http://www.jivephotography.com/2008.htm I'm looking to have the section FEATURED UPCOMING EVENTS scroll down as the user scrolls the page, or at least the fliers.
