DropDown from Odata needed in the xml view

Hi Experts,

We are using SAP fiori - HCM Apps customisation. We need to implement a drop down and the drop down is coming from a Odata.

For Ex: Odata : /sap/opu/odata/sap/ZHCM_ENH_LEAVE_REQ_SRV/

Now i need to populate the drop down using this Odata as a Xml view. I have S1Custom.controller.js and S1Custom.view.js

This Odata will supply 3 values in the drop down. It will be Full Day, Part day-First half and Part day-Second half. (under leave management in HCM-Fiori Extension).

I tried with static <core: items> <code:item> .... tags which is displaying in xml. Now i need to change it to odata to xml view.

needed your help..

What changes i need to do in view and controller.????

Veera P,
