I have spend days researching how to create a custom field of type select and be able to add in the options. I can create the json as such:
{
"name": "My custom select list",
"description": "Simple select list with some dropdown options",
"type": "com.atlassian.jira.plugin.system.customfieldtypes:select"
}
using /rest/api/2/field
but I have not found a way to enter the list of options. Certainly this can be done as part of this json.
