Hello,
I've having trouble figuring out how to use <html:select>.. I've read
through the struts docs, and I can see all of the available properties to
set, like which value I want selected, but it doesn't say how to set what
the list of options are. Am I just plain missing something?
Thanks,
Kenny Smith

Options go in the body of the <html:select> tag. You can use one or
more <html:option> tags, and/or one or more <html:options> tags. If
you're using Struts 1.1, you can use <html:optionsCollection>, which
attempts to improve the syntax of the <html:options> tag.
All of those are discussed in the HTML taglib users guide. It's true
that the doc for <html:select> doesn't really discuss how you handle
the actual options... You may also want to consult the API doc for
the taglib packages, which complements the user's guide.
<http://jakarta.apache.org/struts/api/org/apache/struts/taglib/html/package-summary.html#package_description>
It doesn't say a lot about options specifically, but it's worth
checking out.

oops, that should have read "..an option and/or options [plural] tag". You
can also put multiple option tags. I'm not sure if you can use multiple
options (plural) tags though.

Yep, the docs are a bit obtuse about the actual usage, aren't they? :)
You put an option and/or option tag inside the select tag, like so:
<bean:define id="myCollection" name="myFormBean"
property="myCollectionField" scope="page" />
<html:select name="myFormBean" property="myField">
<html:option value="-1">
Please choose something.
</html:option>
<html:options collection="myCollection" labelProperty="key"
property="value" />
</html:select>
Here, the option tag will ouput "Please choose something" as the label for
the top option in the rendered html tags, with -1 as the value. The options
tag points to a Collection object (or an array) in some scope containing a
list of beans with getKey() and getValue() methods which return the value
for the option label and the value for the option value, respectively.
Note that in this example, I defined the Collection Object in page scope
using a bean:define tag that references a form bean field, but it just as
easily could have bean an Object already in session or request scope (placed
there by an Action or something) named "myCollection".
