[thelist] DHTML expanding lists

[Steve Clason]

Opencube offers a Perl script at http://www.opencube.com/ that does what you
describe (look at the left side navigation.) It's flaky in Netscape and
broke in Opera from what I can tell, but it might help.

> I have been banging my head around here for a few days working on what I
> thought was a simple implementation of an expanding DHTML listing.
> Specifically, the project I am working on requires a listing of data
> with one level of data underneath. For example:
>
> LINK 1
> LINK 2
> LINK 3
>   link 3.1
>   link 3.2
>   link 3.3
> LINK 4
>   link 4.1
>   link 4.2
>   link 4.3
> LINK5
> LINK 6
>
> The tricky part is this listing of data is contained within a table and
> varies in vertical position based on the information needed for the page
> (i.e. the number of elements above link 3 will vary from page to page).
> Secondly, links 1,2,5,6 are not part of the expanding list, rather they
> are regular links to other pages. So, basically if the visitor clicks on
> link 3 the below main links (4,5,6) would move down accordingly based on
> the amount of links contained under link 3, with the same being true for
> link 4. The visitor would then see the exposed sub-links of 3.1,3.2,3.3.
> I have tried several scripts form a few places (DHTMLCentral,
> DynamicDrive, etc.) but they are all called using absolute positions and
> require the setting of a container height for the possible amount of
> space needed to display the items.
>
> I hope I am making some sense here. All I really need it to do is when a
> visitor clicks on a link which contains sub-links the main links below
> it move down to accommodate the listing of sub-links. Also, when a
> visitor "opens" a link (in the case number 3) and then opens another
> link containing sub-links (in the case link 4) then the previously
> opened one closes and the newly requested one opens. Nothing too hard,
> right? Also, I do not care about persistence across clicks so when the
> visitor returns to the page the proper link is still "open."
