Q:

ng-options with disabled rows

Is it possible to use ng-options that it will render into disabled rows based on criteria? 
this:
 <select ng-options="c.name group by c.shade for c in colors">

maybe possible to turn into something like this:
 <select ng-options="c.name group by c.shade for c in colors | disabled(c.shade)">

and let's say via a filter that could return disabled='disabled' for all the colors that have shade = "dark"
<select>
   <optgroup label="dark">
      <option value="0" disabled="disabled">black</option>
      <option value="2" disabled="disabled">red</option>
      <option value="3" disabled="disabled">blue</option>
   </optgroup>
   <optgroup label="light">
      <option value="1">white</option>
      <option value="4">yellow</option>
   </optgroup>
 </select>

@lucuma's answer (originally the accepted answer) was correct, but by now should be updated, because this was fixed in Angular 1.4. See the docs of ng-options which also contains an example.
I'm using Angular 1.5 and this works for me:
View
<select ng-model="$ctrl.selectedItem" ng-options="item as item.label disable when item.disabled for item in $ctrl.listItems">
Controller
vm.items = [
    { id: 'optionA', label: 'Option A' },
    { id: 'optionB', label: 'Option B (recommended)' },
    { id: 'optionC', label: 'Option C (Later)', disabled: true }
];
vm.selectedItem = vm.items[1];

As pointed by @Lod Angular added support for this in 1.4.0-beta.5.
For angular js >= 1.4.0-beta.5.
<select ng-options="c.name disable when c.shade == 'dark' 
group by c.shade for c in colors">

And for angular js < 1.4.0-beta.5 refer the solution below:
Similar to the one given by @lucuma but without jQuery dependency.
Check this http://jsfiddle.net/dZDLg/46/
Controller
<div ng-controller="OptionsController">
    <select ng-model="selectedport" 
        ng-options="p.name as p.name for p in ports"
        options-disabled="p.isinuse for p in ports"></select>
    <input ng-model="selectedport">
</div>

Directive
angular.module('myApp', [])
.directive('optionsDisabled', function($parse) {
    var disableOptions = function(scope, attr, element, data, 
                                  fnDisableIfTrue) {
        // refresh the disabled options in the select element.
        var options = element.find("option");
        for(var pos= 0,index=0;pos<options.length;pos++){
            var elem = angular.element(options[pos]);
            if(elem.val()!=""){
                var locals = {};
                locals[attr] = data[index];
                elem.attr("disabled", fnDisableIfTrue(scope, locals));
                index++;
            }
        }
    };
    return {
        priority: 0,
        require: 'ngModel',
        link: function(scope, iElement, iAttrs, ctrl) {
            // parse expression and build array of disabled options
            var expElements = iAttrs.optionsDisabled.match(
                /^\s*(.+)\s+for\s+(.+)\s+in\s+(.+)?\s*/);
            var attrToWatch = expElements[3];
            var fnDisableIfTrue = $parse(expElements[1]);
            scope.$watch(attrToWatch, function(newValue, oldValue) {
                if(newValue)
                    disableOptions(scope, expElements[2], iElement, 
                        newValue, fnDisableIfTrue);
            }, true);
            // handle model updates properly
            scope.$watch(iAttrs.ngModel, function(newValue, oldValue) {
                var disOptions = $parse(attrToWatch)(scope);
                if(newValue)
                    disableOptions(scope, expElements[2], iElement, 
                        disOptions, fnDisableIfTrue);
            });
        }
    };
});

Note: This solution doesn't work with group by as rightly pointed by everyone. Refer the solution below by @DHlavaty if you are looking to make it work with group by.

A:

Angular added support for this in 1.4.0-beta.5
<select ng-options="c.name disable when c.shade == 'dark' group by c.shade for c in colors">
