//selectize.js: http://brianreavis.github.io/selectize.js/ (brianreavis/selectize.js)
//http://jqueryvalidation.org (jzaefferer/jquery-validation)

//configure jquery validation
$("#commentForm").validate({
	//the default ignore selector is ':hidden', the following selectors restore the default behaviour when using selectize.js
	//:hidden:not([class~=selectized]) | selects all hidden elements, but not the original selects/inputs hidden by selectize
	//:hidden > .selectized | to restore the behaviour of the default selector, the original selects/inputs are only validated if their parent is visible
	//.selectize-control .selectize-input input | this rule is not really necessary, but ensures that the temporary inputs created by selectize on the fly are never validated
	ignore: ':hidden:not([class~=selectized]),:hidden > .selectized, .selectize-control .selectize-input input'
	//optional: add rules etc. according to jquery-validation docs
});

if($("#commentForm").valid()) { 
  alert("this form uses some selectize comboboxes and is valid!"); 
}

Thank you for this!
