To pass a parameter to the viewmodel, see the [ParameterValueConverter](#parametervalueconverterttargettype) section.

#### BindableDropdownField

The `BindableDropdownField` allows the user to pick a choice from a list of options. The `BindingSelectedItemPath` attribute is optional.

```csharp
public class DropdownFieldViewModel : IBindingContext
{
public DropdownFieldViewModel()
{
var items = new ObservableCollection<string>
{
"Value 1",
"Value 2",
"Value 3"
};

Items = new ReadOnlyProperty<ObservableCollection<string>>(items);
SelectedItem = new Property<string>("Value 1");
}

public IReadOnlyProperty<ObservableCollection<string>> Items { get; }
public IProperty<string> SelectedItem { get; }
}
```

```xml
<ui:UXML xmlns:uitk="UnityMvvmToolkit.UITK.BindableUIElements" ...>
<uitk:BindableDropdownField binding-items-source-path="Items" binding-selected-item-path="SelectedItem" />
</ui:UXML>
```

#### BindableListView

The `BindableListView` control is the most efficient way to create lists. It uses virtualization and creates VisualElements only for visible items. Use the `binding-items-source-path` of the `BindableListView` to bind to an `ObservableCollection`.
