I want to disable one of my three select in the lightbox. What’s method can use?
You can try to use the following approach:
scheduler.form_blocks.select.set_value=function(node,value,ev){
var selects = document.getElementsByTagName(“select”);
selects[0].disabled = true; /* 0 is index of the select that should be disabled*/
node.firstChild.value = value;
}
