How to Implement 'Multiple Project Picker' like 'Multiple Issue Picker'

[nallu]

I have seen field type called 'Multiple Issue Picker' in JIRA. Similarly, I want to implement 'Multiple Project Picker'  custom field. Can anyone please guide me how to do it and where to start?

If there are any documentation that would be really helpful. 

Thanks In Advance!!

Hi,

Just saw your post about wanting a Multiple Project Picker custom field like the Multiple Issue Picker.

Jira doesn't offer this natively (only single project picker), but we have an app called Multi Project Picker Fields that does exactly that:

- Select multiple projects in one custom field  
- Fully Forge-based → more secure and native feel  
- Works in issue view, create, edit, transitions, and bulk edit
- Field context configuration (filter by category/type or specific projects)  
- Native JQL support + clickable projects in read-only view  
- Shows “Archived” or “Not found” labels when needed  

It’s a clean, modern solution for use cases like cross-project dependencies, affected projects, or portfolio tracking.

Happy to answer any questions if you give it a spin!

You will need to write a custom field app to provide this.
