How to set up sub category based on category in incodent form. ex - sub-category should be displayed based on specific category

[Amit95]

When you select category as Hardware - it should only display sub category related to Hardware.

if you select category as Software - it should only display sub category related to Software.

However when the category is made dependent it doesnot show any sub-category. 

ex- if none is selected - it shows all values in the subcategory - however if i select any category as hardware or software and then no option is displayed in sub-category.

please let me know if there is any way to take remote and help me understand the issue.

One workaround you can use to prevent Sub-categories being chosen before a Category is to either hide the field or make it read only until a Category has been chosen. This way you don't have to try to reverse engineer what Categories to show dependent upon what Sub-Category has been chosen.

Not only do you have to make the Sub-Category dependent on Category, you must also make the choice values within the Sub-Category choice list dependent upon their corresponding Category values.
