alphabetical order

Absolutely. You can set them to sort in alphabetical order with the orderBy option in the list viewer like this:

$options['orderBy'] = 'name';

What I would do is create a section for "members" and have fields for "group" (which would be a pulldown Line Officers, etc), name, and so on. The make that page a list viewer and sort by name then group like this:

$options['orderBy'] = 'name, group';

Then here's the trick. Call the "foreach listrows" code multiple times, having each time just show one group. Like this:

<h1>Line Officers</h1>
<?php foreach ($listRows as $record): ?>
<?php if ($record['group'] != "Line Officers") { continue; } ?>
Name: <?php echo $record['name'] ?><br/>
Title: <?php echo $record['title'] ?><br/>
<br/><br/>
<?php endforeach ?>

<h1>Executive Officers</h1>
<?php foreach ($listRows as $record): ?>
<?php if ($record['group'] != "Executive Officers") { continue; } ?>
Name: <?php echo $record['name'] ?><br/>
Title: <?php echo $record['title'] ?><br/>
<br/><br/>
<?php endforeach ?>

That will also let you format each group differently if you want.

Hope that helps. Let me know how it goes.
