Question

How to tell if a drop down has options to select?

Answer 1

if ($("#myselect option").length > 0) {
  // Yay we have options
}

Answer 2

var menu = getElementById("select_id");
if(menu.options.length) {
    // has children
} else {
    // empty
}

Answer 3

var hasOptions = !!$('#theSelect option').filter(function() { return !this.disabled; }).length;

maybe? This looks for <option> elements that are not disabled.
