jQuery select box with disable-able options

I'm looking for a jQuery/JavaScript select box for my HTML forms. The specific requirement in my case is that I need to be able to disable certain options in the control's menu. I'd like to know if anyone has found a plugin that allows me to do this, prefera开发者_如何学编程bly easily by using something like

$("#selectControl").change(function()
{
    $(this).find(":selected").attr("disabled", "disabled");
});

Of course, the attr() function won't work on a generated element, but is there a jQuery plugin that has a wrapper for this functionality?

EDIT

To make myself clearer, I'll say it differently: I have an HTML structure that looks like a nicely styled select box, with the hidden actual <select> control behind it. It's possible to disable an <option> in the <select>, but not in most jQuery plugins for styling select boxes. I'm asking if there is a plugin out there that will allow me to disable certain options in the prettified <select> element.

Thanks,

James

I'm not sure I'm tracking on your question, but the code snippet below operates on a dropdown, to hide certain options:

//show them all
$('#<%= ddlRank.ClientID %> span').each(
    function () {
        var opt = $(this).find("option").show();
         $(this).replaceWith(opt);
    }
);

//hide unrelated
var selectionLost = false;
$('#<%= ddlRank.ClientID %> option').each(
    function () {
        if ($.inArray($(this).val(), related) == -1) {
            if ($(this).attr("selected")) {
                $(this).removeAttr("selected");
                selectionLost = true;
            }
            $(this).wrap("<span>").hide();
        }
    }
);  

The secret sauce (to hide them, in conjunction with the "show all" code) is:

$(this).wrap("<span>").hide();

Well, it turns out I didn't look hard enough. For those who want the same thing as myself, I found this plugin. To get my "disable on select" behaviour, I used the jQuery tie plugin which is linked to on the page in the URL somewhere. This is a bit of a hefty selectbox plugin, but minified it should be fine. The box is styled very easily with CSS and can be done entirely without images using the border width trick. If I get enough interest, I'll write a tutorial on how to style these boxes.

EDIT

The plugin linked above didn't actually work very well, so I just wrote my own. I'll post a link to it some time if anyone wants to have a look.
