  let content = anchorTag;
  const links = anchorTag;

  // if identifyUrlHash matches one of the links, use that as active tab
  // if no match found, use first link as initial active tab
  const identifyUrlHash = window.location.hash;
  active = $(links.filter(`[href="${identifyUrlHash}"]`)[0] || links[0]);
  active.addClass("active");

  content = $(active[0].hash);

  // hide the remaining content
  links.not(active).each(element, (subindex, subelement) => {
    $(subelement.hash).hide();
  });

  $(element).on("click", "a", (event) => {
    event.preventDefault();

    // old tab inactive
    active.removeClass("active");
    content.hide();

    // update variables with new link and content
    active = $(element);
    content = $(element.hash);

    // make tab active
    element.addClass("active");
