      offset: 100, // Menu item will active before scroll to a matched section 100px
      scrollContainer: '.scroll-container' // Listen scroll behavior on `.scroll-container` instead of `window`
    // init:
    scrollSpy(document.getElementById('main-menu'), options)

      smoothScroll: true,
      // customize scroll behavior,
      // - default: Element.scrollIntoView({ ...smoothScroll, behavior: 'smooth' })
      // - customize: you can define your scroll behavior. Ex: use `jump.js`, jQuery, .etc
      smoothScrollBehavior: function (element, options) {
        // use `jump.js` instead of the default scroll behavior
