Popup Menus

• A popup menu allows the user to select one of several predefined menu entries, and only takes up a small amount of screen space.
• Like a radio button, only one field can be chosen at a time.
• The Perl CGI construct to create a popup menu would be as follows:
  

  # Generate a popup menu
  print $query->h1('Choose from the following menu');
  print $query->popup_menu({-name=>'PopupOne',
  			  -values=>['First Choice', 'Second Choice', 
  				    'Third Choice', 'Fourth Choice', 
  				    'Fifth Choice'],
  			  -defaults=>'Fifth Choice'});
  

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

      # Extract out whatever the contents of our popup area were.
      my $textInput = $query->param(-name=>'PopupOne');
      print $query->hr();
      print $query->p('The popup selected was:'), $query->br();
      print $query->em({-align=>'center'}, $textInput);
      print $query->hr();
