Bind service to dropdown box

HI,

Im farily new to data binding and I need to take this Odata service and bind it to dropDownBox of UI5

http://services.odata.org/V4/Northwind/Northwind.svc/

for example the values should be collection name and if user select something it should bind to model property

that if user enter to this ui again he see the value that he selected

e.g.

in the beginning the list should be empty and when the user click on

the dropDwonBox it will open the list of

Categories

CustomerDemographics

Customers

etc

when the user select for example Customers this value should be bound to the model that

when he open the page/grid again the selectedValue should be Customers

Thanks,

Joerg
