In app/js/script.js file you can find the init function which contains all template functionalities:

var dannys = { 
    init: function(){ 
        this.CacheDom();
        this.BindEvents();
        this.enablePageLoader();
        this.enableShopMainSlider();
        this.enableShopMainSliderNav();
        this.enableTestimonialSlider(); 
        this.enableParallax(); 
        this.enableRelatedBlog(); 
        this.enableShopRelatedItems();
        this.enableStickyHeader();
        this.enableIsotope(); 
        this.enableMainMenu(); 
        this.enableMobileNav(); 
        this.enableReservationForm();
        this.enableRevolutionSlider(); 
        this.enableMailchimp(); 
        this.initContactForm();         //Object Fit Cover 
        objectFitImages();  },
       [...]

Each functionality can be disabled by removing or commenting the specific function which is located at the beginning of this file.

Also you have the possibility to add new functionalities by adding new functions which are called in the template init function.
