added expand menu for enum

Problem

Currently, enum's do not display descriptions or have an expand menu.

Solution

With this PR I've added an expand menu for enums. I still need to add descriptions in a future update.

• I've added an explanation why this change is needed.
• I've added a changeset (pnpm changeset).
• I've added tests for the regression or new feature.
