Hi Hector,
Thank you for contacting Syncfusion Support.
In our current implementation we do not have navigation mode support for windows phone’s SfTreeNavigator control.
In Windows phone’s SfTreeNavigator control, its behavior is designed in extended mode by default and there is no support to change to navigation mode. Please refer the attached screenshot in which the extended mode behavior of SfTreeNavigator control is shown.
