Scrolling Lists

• The scrolling list will display a long list (scrollable if necessary) that contains a variety of choices.
• You can specify the -multiple=>'true' option to allow more then one menu entry to be selected simultaneously.
• Otherwise, the construct mimics the behavior of a radio button.
• The Perl CGI construct to create a scrolling list would be as follows:
  

  # Generate a scrolling list
  print $query->h1('Choose from the following list');
  print $query->scrolling_list({-name=>'ScrolllistOne',
  			      -values=>['First Choice', 'Second Choice', 
  					'Third Choice', 'Fourth Choice', 
  					'Fifth Choice'],
  			      -multiple=>'true',
  			      -defaults=>'Fifth Choice'});
  

• The Perl CGI construct to then later extract the contents of this menu would be
  

      # Extract out whatever the scrolling list was
      my @textInput = $query->param(-name=>'ScrolllistOne');
      print $query->hr();
      print $query->p('The scrolling list selects were:'), $query->br();
      print $query->em({-align=>'center'}, @textInput);
      print $query->hr();
