directory tree structure

[technotool]

HI,

I am helping to make a php app for some vets. basically, when the vet sees an animal they create an encounter by inputting the information into a form.  Each encouter is unique for a given date.  Of course the form from the encounter gets stored in a MySQL database. easy enough. The vets now want a directory tree of each encounter for a given animal.

so for example, the vet clicks an animal, SPOT ==> a directory tree (I am calling this a directory tree but really it is an encouter tree) pops up with the animal's name as a heading and each encounter form date as a branch.  I mean I think that I can pull each date from the MySQL database stick it in a table format-- but how do you make the lines that we see with a directory tree.  Is there some prepackaged script somewhere.  Thanks in advace for taking the time to read this. technotool.

I applied this scenario to a similar situation. I used '+' and '-' images (hehe, used trusty paint) and depending on if the branch can be explored, added either a minus or plus image.
