Show the options in a single select list based on the issue type

Question

I have a Single Select Custom Field and it has the values, say, A,B,C,D,E,F,G.

If I select an issue type by name Task, then Single Select Custom Field should only have A, B, C options.

If I select an issue type by name Enhancement, it should show D

If I select an issue type by name User Q & A, it should show E, F, G

Other issue type selection should show only D

How do I achieve this?

Go to the list of custom fields in Admin -> Issues -> Custom fields.

Find your select list and hit "configure".

Add a context, giving it the options A, B and C, then tell it the context is for "Tasks"

Add another context for Enhancement with option D

Add another context for User with E, F and G

Let the default context have only D

You may need to use some custom scripting to make this happen.  Take a look at Adaptivist's Scriptrunner.
