My site uses the chocolate style sheet from w3.org and as such is fairly dark. I was wondering if there is a way to force the + and - symbols on trees to be a different color (ie. white)

Nope, you can't. We're stuck with the default GIF images.

I have seen in the source of the #tree tag, the beginnings of code to allow specification of URLs of your own images to replace the defaults. You could always finish that off, and supply a patch of course =).

Martijn, I'd like to see that patch... I've been thinking about doing just this thing. I created a myTree product just to change the icons, which seems silly. I'd rather have the original treetag do this.

I don't want to be a PITA - but, me too. I implemented an SQL-based dynamic tree tag DTML instance based on the 'good stuff' from Phillip Eby et al - one of my users found the totally unreleased 'beta' site where I had it running and (after saying how cool it was) then reeled off a list of cosmetic changes that he wanted doing (open & closed book icons, differently emphasised text for the 'active' leaf etc.) sheesh! ...users. And before anyone says 'you do it' - I can't...yet. I'm not revved up enough on Python methods etc. to do it yet, but considering I'm basing our 3-year project on Zope, as they used to say in 'StingRay' "anything can happen in the next half hour!" tone. ps our site is http://nle.ncl.ac.uk/ - navigate to the demo area and click on the 'database driven' section to see the SQL menu stuff in action.

Note that I did not implement the 'childless_decoration' attribute. This is a quick patch...

I used my lunchbreak to add this as well, because it looked ugly without: Example: <!--#tree opened_decoration="/HelpSys/hs_obook" closed_decoration="/HelpSys/hs_cbook" childless_decoration="/HelpSys/hs_dnode"--> Here the plus and minus symbols are replaced by the help system opened and closed book icons. Nodes without children are displayed with the helpsystem document icon. This is a new patch, _replacing_ the previous one I posted (you did keep a copy of the old version, didn't you?). Again, I'll post this patch to the Collector.
