I display a hash reference in a  template.  It works well but is there a
way I can sort it by SNAME instead of ID?
<ul class="list-group fancy-list-items">    <!-- <ul
class="list-group checked-list-box"> -->
              <table style="width:100%">
                 <% FOREACH ID IN Pats.keys.sort %>
                 <tr class="list-group-item">
                   <td width="70"><% Pats.$ID.SNAME %></td>
                   <td width="75"><% Pats.$ID.ANAME %></td>
                   <td width="35"><% Pats.$ID.SSN %></td>
                   <td width="35"><% Pats.$ID.YR %></td>
                   <td width="250"><% Pats.$ID.CHNAME %></td>
                   <td width="550"><% Pats.$ID.DESCRIP %></td>
                   <% END %>
                 </tr>
             </ul>
             </table>
It looks like you have a hash of hashes. Is that correct?

Anyway, you can pass "sort" the name of the key that you want sort on.

<% FOREACH Pat IN Pats.sort('SNAME') %>
<tr class="list-group-item">
   <td width="70"><% Pats.SNAME %></td>
   <td width="75"><% Pats.ANAME %></td>
   <td width="35"><% Pats.SSN %></td>
   <td width="35"><% Pats.YR %></td>
   <td width="250"><% Pats.CHNAME %></td>
   <td width="550"><% Pats.DESCRIP %></td>
</tr>
<% END %>
