Search combo box

An editable combo box that filters its items as you type. FilterMemberPath acts like DisplayMemberPath for the filter.

The chevron on the right opens the list, as do Up and Down. Opening it that way shows every choice, even once an item is selected : the text left behind by a selection is not a search, so it does not filter the list down to the item already picked.

<inputs:ComboBoxSearch ItemsSource="{Binding Countries}"
                       SelectedItem="{Binding SelectedCountry}" />
