The calendar dropdowns stay disabled until options are loaded. If no calendars are found, check that the URL points to a CalDAV calendar home or calendar URL for the account, and that the account has at least one event calendar available.
+
 After saving, a new **tab** appears in the panel for that provider. You can have multiple instances of the same type (e.g. two Jira configurations) and reorder tabs by dragging.
