Search fields & info panels can be used in the Jira Service Management create request. Then can also be combined into complex use cases like nested / dependant searches and info panels.
While in the create request screen only
user values can be accessed and used for dependancies. Other issue values can only be used after the ticket is created.
Customer Portal - Create Request
To enabled a search field or info panel in the create request you have to enable the
Enable JSM Create Request option in the field configuration.

The values selected in the create request will be saved to the issue like a normal search field and be readonly for the customer.
