Как зафиксировать маленький слайдер в slick slider?

jQuery(document).ready(function($) {
  $('.slider-blocks').slick({
    nextArrow: '<img class="slick-btn-next" src="../img/sri1.png" alt="next">',
    prevArrow: '<img class="slick-btn-prev" src="../img/sle1.png" alt="prev">',
    slidesToShow: 1,
  	slidesToScroll: 1,
  	fade: true,
    asNavFor: '.slider-nav'
  	});
  $('.slider-nav').slick({
    asNavFor: '.slider-blocks',
    slidesToShow: 4,
    slidesToScroll: 4,
    focusOnSelect: true,
    });
});
