Answer 1

You just need a nested ng-repeat for the childrens.

<span ng-repeat="something in somethings"> 
  <h3>{{ something.name }}</h3>
  <select>
    <option ng-repeat="child in something.children"> {{ child.name }}</option>
  </select>
</span>

I am guessing how you want to display them but i hope it can give you some ideas. Here is a JsBin

Does this JSFiddle do what you want? It takes your nested structure and makes a flat structure from it. It will then use that flat structure for display.

<select ng-model="selected">
    <option ng-repeat="option in tree" ng-bind-html-unsafe="option.displayName" value="{{$index}}">{{ option.displayName }}</option>
</select>

$scope.tree = [];
function buildTree(data, depth) {
    for(d in data) {
        var c = angular.copy(data[d]); //copy object
        delete c['children'];  //we dont want to copy children
        c.displayName = Array(depth*4).join("&nbsp;") + c.displayName;
        $scope.tree.push(c);
        buildTree(data[d].children, depth+1);
    }
}
buildTree($scope.data, 0);

I use ng-bind-html-unsafe because you wanted to display it like a tree, I feel like that is best accomplished by adding whitespace before the nest option, which is done with the   .
