I have this form below, and I’m using Bootstrap forms validation inside a select input field. I’m also using the Select2 library to search for a specific option from the options list. I’m using the class (js-example-basic-single) to make Select2 work. However, when I use it, and upon clicking the submit button, validation works for all form fields except inside the select field. When I remove this class (js-example-basic-single) from the select input field, validation works normally inside the select field. I don’t know the reason for this and I need assistance.
// Example starter JavaScript for disabling form submissions if there are invalid fields
(() => {
'use strict'
// Fetch all the forms we want to apply custom Bootstrap validation styles to
const forms = document.querySelectorAll('.needs-validation')
// Loop over them and prevent submission
Array.from(forms).forEach(form => {
form.addEventListener('submit', event => {
if (!form.checkValidity()) {
event.preventDefault()
event.stopPropagation()
}
form.classList.add('was-validated')
}, false)
})
})()
$(document).ready(function() {
$('.js-example-basic-single').select2();
