Hi Dan, I've done a fair amount of work with something called the XMLHttpRequest object that can be used quite successfully to accomplish this. It is compatible with all of the major browsers, and I have gotten it up and running in IE, Firefox, Netscape, and Safari for our own applications.
Basically, you make a Witango page that returns an XML document that contains the information you are interested in and parse that in javascript to create your drop down lists. The benefit to this is that you do not need to do a page refresh every time the user changes an option, since the XMLHTTPRequests are called in the background on a currently loaded page. Google makes extensive use of this in gmail and maps, so there is some industry support. Check out this URL for more details: http://www.xml.com/pub/a/2005/02/09/xml-http-request.html There are some browser specific tweaks you need to pay attention to, such as IE's non-standard object names (their XMLHTTPRequest is created like an ActiveX object) and Safari's weird casting when creating DOM objects (you need to be careful with the names you give your elements in your XML documents or they end up being cast incorrectly) but it is definitely doable with a little work. ********************* Mike Arace Web / Database Developer, NIDB Contractor DECA/CIT/NIH -----Original Message----- From: Dan Stein [mailto:[EMAIL PROTECTED] Sent: Monday, May 23, 2005 10:54 AM To: [email protected] Subject: Witango-Talk: Drill down lists I need to create a list like this Generic Drug Name Formulations Programs I want the users to see a lists of the generic drugs and then when they click on the arrow they see the list of formulations then find their formulation and arrow drops down list of programs I need it to be compatible on ALL browsers Mac and PC So I am thinking XML is better than JS Can anyone either point me to a component of else a best resource to start at. Project is for a non-profit so not lots of bucks to spend on consulting but if someone wanted to help me with this part and we could agree on a fee I am willing to learn of course.
