2. the view
 
 
3. Javascript Code to get categories based on department id
 
 
 4. Get sub Method
 
 
 
5. Error Occures as Undifine (If there is 3 categories for a particuler department Id that will display 3 undifines which means Value and Text is not passed from contaller.But the count is passing)
