I have a jenkins job with multi select extended choice parameter. There are list of elements in a parameter. So, my requirement is I want to allow users to select multiple parameters excluding first element in a parameter. Means user should not able to select first element with other elements in a parameters. I am using jenkinsfile to create parameter.
Like shown above, users should not able to select 'None' with any other element in a parameter. Does anyone know how to do this?
