I can see a colour swatch radio list in nuPickers screenshots: https://our.umbraco.org/projects/backoffice-extensions/nupickers/

I need to create something like this for my umbraco doc type. How to do it? So far I found this thread but still have no clue how to create the radio with image labels: https://our.umbraco.org/forum/umbraco-7/using-umbraco-7/53715-Datatype-image-list

I have created a new data type nuPickers: XML RadioButton List, ith Xml Data as Media, XPath as //Image, Key XPath as @id, Label XPath as @nodeName.

I have created a macro and this macro partial view:

@inherits Umbraco.Web.Macros.PartialViewMacroPage
@{
    <span>@Model.MacroParameters["key"]</span>
}

and selected it to use for my nuPickers data type.

I have of course added a macro parameter with alias key.

So far nothing displays in my content edit page and I can't see how I can set various images with radio buttons to display for selection in my content edit page.

How to set it up?
