Hi, 

How can I add a button under 'More' tab that creates a subtask?

is there way to do this without editing workflow?

Thank you

Hi, @asdf 

As @John Funk said, there are 2 variants.

1. You can make Jira Automation rule, which is triggered manually, limit it visiblity to limited groups of users, and set action, that must be done. It's most easy way.

2. ScriptRunner is more tricky, not so easy to add new function, and needs knowledge of coding, but it is more flexible.

Hi asdf,

You should be able to create an Automation Rule or a ScriptRuner script to do that.

For Scriptrunner, look to the "fragments" function, which lets you insert items into almost any part of the UI.

I am slightly curious as to why you want to do this though, as there's already a "create subtask" link in the issue menus (it only appears when it is a valid option though - you have one or more sub-task types available in the project)
