jquery validate plugin in combination with other plugin

jquery validate plugin in combination with other plugin

One plugin I use for input in select boxes is   this ...and more specifically I currently use the multiple select feature.

The validate plugin works only with form.
My aim is to test if the user has entered a value in the select box and if not present a message to him....something the validate plugin can do of course... but only for forms.

So...I want to ask what are my alternatives in a case like the above.
Currently I just present an alert box to the user by using this type of  code:

  1.  if ($.trim((this.$('#name').val()))==='')
  2.              {alert('No name is inserted');
  3.               return false; 
  4.              }

What can I do here,if anything can be done?
As I said not form tag here,just the HTML markup produced by Chosen plugin.

Take a look at this  fiddle ...click on the calendar to make the dialog box appear.
Type something in the title box and delete it....you will see it has no effect-no error message is produced by the validate plugin,as it should

And at the JS window,in the bottom you will code relevant to the validation plugin.... my problem of course is that it has no effect.

Thanks
