Need to disable already selected options in select box using jQuery. I'd like it to grey out like asmselect.

Test my example here.

//JS
$("#theSelect").change(function(){          
  var value = $("#theSelect option:selected").val();
  var theDiv = $(".is" + value);

  theDiv.slideDown().removeClass("hidden");
});


$("div a.remove").click(function () {     
  $(this).parent().slideUp(function() { $(this).addClass("hidden"); }); 
});

//HTML
<body>
<div class="selectContainer">
    <select id="theSelect">
        <option value="">- Select -</option>
        <option value="Patient">Patient</option>
        <option value="Physician">Physician</option>
        <option value="Nurse">Nurse</option>
    </select>
</div>
<div class="hidden isPatient">Patient <a href="#" class="remove" rel="Patient">remove</a></div>
<div class="hidden isPhysician">Physician <a href="#" class="remove" rel="Patient">remove</a></div>
<div class="hidden isNurse">Nurse <a href="#" class="remove" rel="Patient">remove</a></div>
</body>​

UPDATED: Here's the finished solution. Thanks to Patrick and Simen.

This will disable/enable the options when you select/remove them, respectively.

$("#theSelect").change(function(){          
    var value = $(this).val();
    if (value === '') return;
    var theDiv = $(".is" + value);

    var option = $("option[value='" + value + "']", this);
    option.attr("disabled","disabled");

    theDiv.slideDown().removeClass("hidden");
    theDiv.find('a').data("option",option);
});


$("div a.remove").click(function () {     
    $(this).parent().slideUp(function() { $(this).addClass("hidden"); });
    $(this).data("option").removeAttr('disabled');
});

This seems to work:

$("#theSelect").change(function(){          
    var value = $("#theSelect option:selected").val();
    var theDiv = $(".is" + value);

    theDiv.slideDown().removeClass("hidden");
    //Add this...
    $("#theSelect option:selected").attr('disabled', 'disabled');
});


$("div a.remove").click(function () {     
    $(this).parent().slideUp(function() { $(this).addClass("hidden"); });
    //...and this.
    $("#theSelect option:disabled").removeAttr('disabled');
});

Add this line to your change event handler

    $("#theSelect option:selected").attr('disabled','disabled')
        .siblings().removeAttr('disabled');

This will disable the selected option, and enable any previously disabled options.

EDIT:

If you did not want to re-enable the previous ones, just remove this part of the line:

        .siblings().removeAttr('disabled');

EDIT:

To re-enable when you click remove, add this to your click handler.

$("#theSelect option[value=" + value + "]").removeAttr('disabled');
