I need assistance hiding custom fields during the issue creation process in Jira

[Ariel Alvarez]

Hi, I'm looking for help with Jira Forge. I need to dynamically hide certain custom fields on the 'Create Issue' screen based on specific conditions.

Hi, @Ariel Alvarez 

The module you need is jira:uiModifications - it hooks directly into the Global Issue Create (GIC) screen and lets you control field visibility at runtime.
In your manifest, declare a jira:uiModifications module pointing to a Custom UI or UI Kit resource. Then in your code, use uiModificationsApi.onInit to grab the context (project, issue type) via view.getContext() from @forge/bridge, and call setVisible(false) on any field you want hidden based on your conditions.
The getFieldById method from the API gives you a handle on specific fields, and from there you toggle visibility.
One thing - this only works on the new issue create experience, not legacy screens. Also make sure your manifest includes scopes like read:jira-work and manage:jira-configuration.
