How to manipulate customfield

[gayatrii]

There is a custom field of type 'Checkboxes' named 'custom1'. it has 3 options as check boxes.
I have a requirement is that if I click option1 checkbox I have to get suboptions(for example checkboxes 4,5).
How to do this in Jira?

Thanks in advance

You don't - checkboxes are checkboxes, not cascading-checks.

The easiest approach is to use a "cascading select" instead.  Or, you could try something horrid with javascript and either two fields or making extra check options appear.  Or use the Behaviours from the Script Runner add on to make two checkbox fields to work together.

Thanks for the quick response Nic. can you please explain the point " use the Behaviours from the Script Runner add-on to make two checkbox fields to work together."
