Binding two entities to dropdownlist in one view

Hi all,

I am a newbie MVC5 and Entity Framework 6. 

I have 3 tables: Employee (id (pk), name, departmentID(fk), jobtileID(pk),...), Department(departmentID(pk), name,...) and Jobtile(jobtitleID(pk), titleName,...).

I would like to buitd a website to allow users to add employee to the database.

The website has a view to list all Employee using EF with these information: id, name, departmentName, titleName,...) in a table.

When an user selects Add new button, a new view allows user to add name, select an department from dropdownlist and select jobtile from another dropdownlist.

While the user selects Edit button a view allows user to edit Employee Information as employee name, department and jobtitle display correctly in edit view.

I want to use zaror to bind data to dropdownlist using dropdownlistfor. 

How to solve this problem. Thank in advanced.
