Collapsable Blocks - a how to.

The other day I posted the question,
http://drupal.org/node/35672
after a couple of days of work, and adding some things. I have a very elegent and workable solution. You can check out www.matthewedmunds.com/aurora for a working example. In order to get the result, I first modified my template (using xtemplate, hope to switch to phptemplate soon), adding a unique id to the content div of the block, mine being content-module-delta, to make sure that nothing had the same id tag. Once each block had its own content ID, that allowed for a div toggle of just the content of the block, leaving the title.

For the simplest solution, you can then take the nice css/javascript code provided on drupal art:
http://www.drupalart.org/togglediv

Which is what got me started. However, once realizing the power that can be had, I dreamed of an icon that could sit in the corner of the block title, and allow for the toggle, changing the image related to the state that div was in. Also needed was the ability to remember the state of a collapsed, or open block from page to page, while a user is navigating through the site. I found that after a little googling, and drupal searching to see if anyone else has ventured here before. I was told the logintobbogin module had a similar setup, but it didnt provide what I wanted from a simple, across the board implentation, not hacking every other mod I have.

I found, a dynamic drive script, Switch Content II, which provides all the necessary functionality. It remembers states.. by default, page to page (I'll get to that in a sec). It allows for an image to give a graphical representation of a state, currently plus or minus, and it allows for the toggle of divs and interesting enough, other ids. So you can really use it for other interesting concepts... e.g. toggling a whole sidebar of blocks if desired. And it played nice with other scripts I'm running.

The script was changed to remove page data from the cookie, to make it only go sitewide. Which is helpful because most of my blocks are run through the whole site. It can still however remember those that are only on certain pages, as that info will exist in the cookie, even if the block is being hidden by drupal to only appear in certain areas. Therefore allowing users customization.

All I did to call the script, is replace the div in the href, with that of the same setup for how the content id would appear, so they would be identical, therefore allowing the script to be coded to every block on the page, to only collapse/expand the block its associated with. Thus adding functionality to every block that will ever be used, or in the future added, without the task of having to modify each block individually.

If there is interest, I'd be glad to post the modified code, and style sheet.
