Adding a custom field in jira for structure plugin

[Navadeep]

Hi ,

We have structure plug-in for JIRA, and we would like to add a custom field within the existing project. For ex. the current project have 4 fields already available. I would like to add a new custom field named "Release-date"

Below are the existing fields available.

KEY  | SUMMARY | Processing |  StartDate | EndDate | <Custom field to be added>

When I tried to add a release-date, the custom field was not available.

Where can I add the entry to the custom field, so that it is available to be added for existing project.(i.e., in place of <custom field to be added>)

Thanks in advance !!

Thanks,
