Property Value List lets editors input multiple primitive values.
The available and supported types are:
`
String
``
Int

DateTime
``
Double
`
The idea is the same as with the `List<T>
`, you add the list as a new property to your model, and the default descriptors match `IList
`Â type and render the correct editor.




Note
The property type does not have to be `
IList
`. The Optimizely descriptors are configured to match the `IList
` interface but they also cover all base ones, so if you prefer to use `IEnumerable
` or `ICollection
` you can do so. All the following declarations are matched by the Value List descriptor.
## Validation
You can apply validation to both the list itself and to the individual items, and you can use `ListItemsAttribute
` to control the number of items in the list:
The attributes that can be applied to individual items are:
## Render a list
To render a list:
To use the `PropertyFor
` helper method you must define a specific Display template, and to do that you must first attach a `UIHint
` to your property:
Then add a _StringsCollection.cshtml_ file to the _~/Views/Shared/DisplayTemplates_ folder.
An example of a Display Template can be seen in the Alloy package:
Add a `UniqueSellingPoints
` property to your page template:
And you will see the following result in on-page edit:
