Re: Help needed on question regarding html:select and html:options...

[Erik Weber]

I don't know exactly how do it using JavaScript. However, I know there's 
a way to do it. But, you'd have to have all list data downloaded to the 
client's browser (could be undesirable depending on list size), so you 
may want to rethink that approach once you figure out how to do it.

Obviously it can be done using ordinary programming on the server side 
(JavaScript can resubmit the page when the first select's value is 
changed, and you can change the collection to be displayed in the second 
select before you resend the HTML).

<html:select property="s1">
       <html:options collection="c1" property="value"
                  labelProperty="label"/>
     </html:select>
<html:select property="s2">
       <html:options collection="c2" property="value"
                  labelProperty="label"/>
     </html:select>
--------------------------------------------------------
when user choose item2 from s1, I want to change the collection in s2 
from "c2"  to "itemC". How can I do that?
