This feature is only available to Admins, and Leads
In order to enter job information for a campaign, the campaign admin first needs to set up the jobs fields. By creating the necessary Section, Field and Responses, you can customize the jobs options to best fit the work that you are doing on your campaign.
Once you have created the Info you need, select the Field that corresponds to your Key Address. The Key Address should be the physical location of the job and should include a location in the response. This is the location that will be mapped as the worksite in Map View.
After selecting the Key Address, you can select your custom Fields for the pertinent information to that campaign.
The Info Administration page explains the difference between Sections, Fields, and Responses.
