Hi Enrique

it depends a bit on what property you wish to display through the property editor.

slightly better documentation would show this as

<umb-property-editor model="vm.model"></umb-property-editor>

where the model is the details of the property you want to display: for example for a toggle this might look like :

 vm.model = {
            Alias = "autoSend",
            Label = "On or Off",
            Description = "Turn this thing on or off",
            Value = vm.myValue,
            View = "boolean",
            Config = 
            {
                { "default", null }
            },
};

The trick here is knowing what goes in the Config element as this can be different depending on the property type - there is not really a quick way to get this information at the moment, other than look at how it might be returned by Umbraco for a content item :

e.g if you look in chrome for network requests to GetById?id= you should be able to drill down, (under the variants tab) to something like this:

which will show you what Umbraco is passing into the Model value when it uses umb-property-editor.

in practice sometimes if you know what the type is you want it's often easier to call the directive for that. e.g for a checkbox this looks like :

<umb-control-group label="On or Off" description="Turn this thing on or off">
 <umb-toggle checked="vm.myValue" 
                        on-click="vm.myValue = !vm.myValue"
                        label-on="on"
                        label-off="off"></umb-toggle>
