I can disable one and one by doing the following:
jQuery('#ListBoxA').attr('disabled','true');
But how can I apply this to multiple elements? This does not work:
jQuery('#ListBoxA, #ListBoxB, #ListBoxC').attr('disabled','true');
UPDATE
Not a lot of markup to show ....
<select id="ListBoxA" size="4" name="countrySelectBox">
<select id="ListBoxB" size="4" name="cityListBox">
<select id="ListBoxC" size="4" name="storeListBox" multiple="multiple">
