The best and the perfect code you'll require to sync two owl carousels so that it slides together. Check the code below
$(document).ready(function () {
// Initialize the first carousel
var owl1 = $('#owl-carousel1').owlCarousel();
// Initialize the second carousel
var owl2 = $('#owl-carousel2').owlCarousel();
// Flag to prevent recursive calls
var changingFromOwl1 = false;
var changingFromOwl2 = false;
// Event listener for owl-carousel1 changes
owl1.on('change.owl.carousel', function (event) {
if (!changingFromOwl2 && event.namespace && event.property.name === 'position') {
changingFromOwl1 = true;
var target = event.relatedTarget.relative(event.property.value, true);
owl2.owlCarousel('to', target, 300, true);
changingFromOwl1 = false;
}
});
// Event listener for owl-carousel2 changes
owl2.on('change.owl.carousel', function (event) {
if (!changingFromOwl1 && event.namespace && event.property.name === 'position') {
changingFromOwl2 = true;
var target = event.relatedTarget.relative(event.property.value, true);
owl1.owlCarousel('to', target, 300, true);
changingFromOwl2 = false;
}
});
});
