Thank you so much, your suggestion to place the begin/end-block into the
subroutine, so it can call itself recursively with that:
% sub expand_tree { begin
<pre>DEBUG</pre>
% my $node = shift;
% foreach my $node_type (keys(%{ $node })) {
<div class="<%= $node_type %>">
<h2 class="service_tree_node_type"><%= $node_type.'s' %></h2>
<ul>
% foreach my $child (keys(%{ $node->{$node_type} })) {
<li><%= $child %></li>
%= expand_tree($node->{$node_type}->{$child}->{'subelements'});
% }
</ul>
</div>
% }
% end -> (@_); }
%
% layout 'default';
%
<div class="container">
<h1>Make yourself at home, <%= $self->session('user_email') %>!</h1>
%= expand_tree($service_tree);
</div>
Thank you!
