It's not exactly clear to me what your requirements are, but I took a 
half hour to cook up a sample for you using Maestro which 
demonstrates radio buttons, checkboxes, and selection menus. Fifteen 
minutes of that was coming up with a list of 20 "channels" :-)

Here is the list subscription page that was automatically generated 
by Maestro:

http://maestro-demo.lsoft.com/list/subscribe.html?mContainer=119&mOwner=G2q2t382p&mListSeqNo=146

Try it out. 

I used the same list of channels to produce 2 "single selection" 
fields, one shown as a set of radio buttons, one shown as a pull-down 
menu; and 3 "multiple selection" fields: one shown as checkboxes, one 
shown as a multiple-select menu (use CTRL-click or SHIFT-click to 
select multiple entries), and one again as checkboxes, but in this 
case I made it a mandatory field so subscribers must select at least 
one, and I told Maestro to use 2 columns of checkboxes instead of the 
default.

This sample list is a "hosted recipient list" (HRL) which means it is 
only stored in Maestro. However, you can also have "hosted LISTSERV 
lists" (HLLs) so that you can have both LISTSERV's flexible header 
keywords AND Maestro's data hosting facilities. HRLs can only be 
announcement lists and can only be sent to using Maestro, but they 
have a very flexible and easy to use target group creation Wizard, so 
that you can send targeted mailings, for example to only people who 
selected ABC and CBS, or who selected any of a subset of channels, or 
other such targeting schemes. HLLs are basically DBMS-based LISTSERV 
lists, so they can be sent to with any email client or with Maestro, 
and they can be discussion lists or moderated lists or announcement 
lists; they can have archives, digests, etc. But the data within the 
HLL is maintained inside of Maestro.

This sample uses the default look. You can easily customize the pages 
for a different look. I'll see if I can locate an example where I did 
some customizations.

This was done using LISTSERV Maestro 2.1. It will become even more 
flexible and even more tightly coupled with LISTSERV in version 3.0, 
coming later this year. And that, of course, is another reason why 
going with Maestro is better than rolling your own: we have a team of 
developers working on this full-time to make it ever easier to use 
and always up-to-date with LISTSERV. We have access to the LISTSERV 
development team so that whenever a desired feature in Maestro 
requires a new feature in LISTSERV, it gets done. 

I hope this is helpful. If there are any other features you'd like to 
see demonstrated, please let me know.
