Random uComponents Multi-Node Tree Picker
I have the below code snippet that renders the selected Multi-Node Tree Picker nodes. I'm looking at how to select a random selection of those nodes.

Model.TreePicker returns umbraco.MacroEngines.DynamicXml - can this be converted to a DynamicNodeList to apply Random? Or is there another way?
```
@inherits umbraco.MacroEngines.DynamicNodeContext                                                     
@{
  if (Model.HasProperty("treePicker") && Model.GetProperty("treePicker").Value != String.Empty) {
    <ul class="features">
      @foreach (var item in Model.TreePicker) {
        var node = @Model.NodeById(@item.InnerText);
    <li>
      <a href="@node.Url">@node.Name</a>
        </li>
      }
    </ul>
  }
}
```

You're going to have to put the items in a seperate list (var myList = new List<DynamicNode>();) (in your foreach loop, do something myList.Add(node) and then after the foreach you can do myList.Random();

@using umbraco.MacroEngines
@inherits umbraco.MacroEngines.DynamicNodeContext
var nodes =newDynamicNodeList();
if(Model.HasProperty("treePicker")&&Model.GetProperty("treePicker").Value!=String.Empty){ 
    foreach(var item inModel.TreePicker){
      var n =newDynamicNode(@item.InnerText);
      nodes.Add(n);
    }
    <ul class="features">
      @foreach(dynamic node in nodes.Random(3)){
        <li>
          <a href="@node.Url">
            @RenderPage("RenderPageMedia.cshtml","thumbnail", node.Thumbnail)
            <div class="description">
              @Html.Raw(node.Name)
            </div>
          </a>
        </li>
      }
    </ul>

Cool! So where did the random go?

By the way, If you're using 4.7.1, you can do Model.HasValue("treePicker") and you don't have to do the empty string check and hasproperty.
