How can I specify which issue fields are displayed on Jira board? I've created a issue type with some custom fields that our users want displayed on the Jira board. Specifically they would like to remove "Component" and add the custom field in its place. Which screen is this that I need to edit? Currently we see issue type, priority, story points and components.
Try going to Board Settings (or maybe it's Configure Board in Server version).
Then choose Card Layout. There you can switch out the fields for the board.
The menu items may be a little different for Server, but you should be able to find them.
