Provide tooltip for custom fields?

[Louise Baker]

When viewing records, if you hover over Status or Type you get very helpful tooltips that explain a bit more about the status/type.

Is there a place to determine a tooltip text for fields such as Component, or a custom field?

There indeed is - but not as a mouseover/popup.

What you can do is add field description (aka help-texts) below fields on issue forms - Create and Edit. You cannot however add it to the issue view screen, only to those two - Create and Edit.

With Custom Fields, you can edit each field individually and add a default description - this will show under the field on Create and Edit forms, as long as Field Configuration does not overwrite it.

Field Configuration is similar - you can modify it and add your own field description, however I should stress - this will affect all issue types in all projects using this Field Configuration. So you likely would only want to do this with custom made Field Configuration under custom Field Configuration Scheme.

Elementary 101, each project uses Field Configuration Scheme, and if you do not change it, it uses System Default. You probably do not want to do this for the System Default scheme. If you want to change the helptext/description of a Component field, then you can simply create your own Field Configuration Scheme and associate it with the project you want to apply it to.

The following page describes this in more detail: https://confluence.atlassian.com/adminjiraserver/specifying-field-behavior-938847255.html

If however you meant strictly "description per value" then the answer unfortunately is nope. The only visible description to the users are on a field-basis, under the field, not as individual value descriptors.
