Problem is solved:
var Webflow = Webflow || []; Webflow.push(function() { // Store cached references to nav elements var sourceNav = $('#sourceNav'); var targetNav = $('#targetNav'); var savedIndex = 0 // Every 200ms setInterval(function() { // Find the index of source slideNav button's active class var index = sourceNav.children('.w-active').index(); if (savedIndex != index) { // Update target slider by triggering a "tap" event on the targetNav corresponding slide button targetNav.children().eq(index).trigger('tap'); } savedIndex = index }, 200); // End interval }); // End ready function </script
