1. Is it possible to create a drop down list in Word?

2. If so is it possible to create sub headings which open up different options - (to help make a long list more readable).

Example

Learning Issues List

Learning Disability
- Disability type 1
- Disability type 2
- Disability type 3
Health Issue
- Health 1
- Health 2
- Health 3
Behavioural Issue
-Behavioural 1
-Behavioural 2
-Behavioural 3

Ideally, I would like the list to show the categories (in bold) and then the sub-categories when selected...

Is that possible?

Unfortunately (for me) it needs to be in Word

Any help would be much appreciated.

Thanks
