Hi all,

Here's what I did to put the accordion style into the tool menu:

in the file galaxy/templates/root/tool_menu.mako
as the last thing in the main function:

<script>
//Init. on document load
   $(function(){
..
..
//~~~here~~~
    });
</script>

I added the following (lifted lovingly from Genboree Galaxy):

  // Init showing/hiding of tool sections.
            $( "div.toolSectionBody" ).hide();
            $( "div.toolSectionTitle > span" ).wrap( "<a href='#'></a>" )
            var last_expanded = null;
            $( "div.toolSectionTitle" ).each( function() {
               var body = $(this).next( "div.toolSectionBody" );
                  $(this).click( function() {
                    if ( body.is( ":hidden" ) ) {
                       if ( last_expanded ) {
                         last_expanded.slideUp( "fast" );
                       }
                       last_expanded = body;
                    body.slideDown( "fast" );
                    } else {
                      body.slideUp( "fast" );
                      last_expanded = null;
                    }
                    return false;
                  });
             });

Note that this overrides the events:{ 'click..'} in the model/view/controller and so is undesirable, but I'm not familiar enough with Backbone to play by its rules.  At least not on a Friday afternoon.

Sincerely,
