Company Field

Couple of queries:

1. When creating a job from the front end there is delivered field called ‘Company’ that a user can select from a drop down. As this is a drop down list how does a user add a new value as there is only an option to choose from the existing companies.

2. In the preview card for ‘Jobs’ this default ‘Company’ field is not visible to be added from the drop down list. I can of       course create a new field but that means there are duplicate fields for what should be the same thing.

Can you help?
