Hi,

I've some questions.

Firstly I want to know if there is a developer mode in umbraco. ie a mode that allows you to test and view the result before publishing it. This is possible in content section by saving the content and not to publish and view it with "Preview" button, but for the developer section when I change (for example) a template, and I want to see the content without publishing it, the problem is that when I click "save" it will change for members. so how do the developer to change and preview before its release to everyone.

secondly for cshtml in template is there a debug tool? Example for this code

<umbraco:Macro  runat="server" language="cshtml">
@inherits umbraco.MacroEngines.DynamicNodeContext
@{ var numberOfItems = 10; }
@foreach (var item in @Model.Children.Where("umbracoNaviHide != true").Take(numberOfItems).OrderBy("UpdateDate")) {
    //do nothing
}
</umbraco:Macro>

if I make a mistake (I write "where" instead of "Where") it does not work, how to find and debug this thing.

Finally (ouuuf :D ),  I think this is simple but I don't find the solution.it's how to fill a Dropdown or a Dropdown multiple?... I create a document type "DocTypeName" with a property "color" dropdown multiple, and when I instantiate the document type it give me an empty dropdown multiple , then how to fill it.?

Tank you very much for your help :)
