FormValidation.io with bootstrap select

I'm using Boost strap 4 and the bootstrap select jQuery plugin.

Im trying to integrate FormValidation.io with my forms. I have got everything working with normal input fields but cant figure out how to integrate it with the select field.

I would like it to be a required field and display the tick icon once a selection has been made.

my FormValidation.io code :

document.addEventListener('DOMContentLoaded', function(e) {
const mydropzone = document.getElementById('mydropzone');

const RoleIdField = jQuery(mydropzone.querySelector('[name="roleId"]'));    

const fv = FormValidation.formValidation(mydropzone, {    
       
    
        fields: {
            first_name: {
                validators: {
                    notEmpty: {
                        message: 'First Name is required'
                    },                        
                    regexp: {
                        regexp: /^[a-zA-Z]+$/,
                        message: 'First Name can only consist of alphabetical characters'
                    }
                }
            },
            last_name: {
                validators: {
                    notEmpty: {
                        message: 'Last Name is required'
                    },                        
                    regexp: {
                        regexp: /^[a-zA-Z]+$/,
                        message: 'First Name can only consist of alphabetical characters'
                    }
                }
            },
            roleId: {
                validators: {
                    notEmpty: {
                        message: 'Please select a Role'
                    },  
                }
            },
           
        },
        plugins: {
            trigger: new FormValidation.plugins.Trigger(),
            bootstrap: new FormValidation.plugins.Bootstrap(),
            submitButton: new FormValidation.plugins.SubmitButton(),
            icon: new FormValidation.plugins.Icon({
                valid: 'fa fa-check',
                invalid: 'fa fa-times',
                validating: 'fa fa-refresh'
            }),
        }
    }
);
});


$('#roleId').on('changed.bs.select', function (e, clickedIndex, isSelected, previousValue) {
// Revalidate the color field when an option is chosen
fv.revalidateField('roelId');
});

My form ID is 'mydropzone' and my select name and id are 'roleId'

Any help appreciated.

Thanks to the developers who answered my email, anyone else that needs to know how this is done:

add this to your css file :

.bootstrap-select i.fv-plugins-icon {
right: -38px !important;

then configure your js like this :

<script>
document.addEventListener('DOMContentLoaded', function(e) {
$('#gender').selectpicker();

const demoForm = document.getElementById('demoForm');
FormValidation.formValidation(demoForm, {
    fields: {
        gender: {
            validators: {
                notEmpty: {
                    message: 'The gender is required'
                }
            }
        },
    },
    plugins: {
        trigger: new FormValidation.plugins.Trigger(),
        submitButton: new FormValidation.plugins.SubmitButton(),
        bootstrap: new FormValidation.plugins.Bootstrap(),
        icon: new FormValidation.plugins.Icon({
            valid: 'fa fa-check',
            invalid: 'fa fa-times',
            validating: 'fa fa-refresh'
          }),
       }
    });
});
</script>
