How can I add another submenu under the submenu?-CodePudding

I tried to use the same pattern in creating submenu, and its displaying but the problem is its already showing when I only trying to view the submenu

<ul >
  <li>
    <div >
      <a href="#">
        <i class='bx bx-collection'></i>
        <span >Patient Information Module</span>
      </a>
      <i class='bx bxs-chevron-down arrow'></i>
    </div>
    <ul >
      <li><a  href="#">Patient Information</a></li>
      <li><a href="#">Patient</a></li>
      <li><a href="#">Dental</a></li>
      <li><a href="#">Immunization</a></li>
      <li><a href="#">Pediatric</a></li>
      <li>
        <div >
          <a href="#">
            <i class='bx bx-collection'></i>
            <span >Pediatric</span>
          </a>
          <i class='bx bxs-chevron-down arrow'></i>
        </div>
        <ul >
          <li><a  href="#">Immunization</a></li>
          <li><a href="#">Deworming</a></li>
          <li><a href="#">Vitamins/Suppliments</a></li>
        </ul>
      </li>
      <li><a href="#">TB Dots</a></li>
      <li><a href="#">OB</a></li>
    </ul>
  </li>
