Unable to get 'None' as options in List

[Khushbu Jowaheer]

Hello All,

I have 3 custom fields:

1. Team(Select list)
2. Category(Cascading list)
3. Supplier (Select list)

When a team is selected, I want these values to populate in my dropdown list for the fields Category and Supplier Name as shown below. I am using behaviour to do my scripting.

For team1:

Category:
None
category1
category2
category3

Supplier Name:
None
value1
value2

For team2:

Category:
None
category4
category5

Supplier Name:
None
value3
value4

I'm able to populate these values: category1,category2,category3 and so on. It's just the None value is not in the list. I've tried to add the null value in my code but that does not work.

Is it possible to do so?

Thanks,
Khushbu

This is the same concept as the question you asked the other day - https://community.atlassian.com/t5/Jira-questions/Unable-to-get-None-as-options-in-List/qaq-p/769031

It's worth continuing there instead of repeating the question.

Could you provide your script?
