Bootstrap Navbar Collapse Not Showing List-CodePudding

I am using bootstrap navbar and I have a collapsible navbar. But I am facing a strange problem, whenever I open my site i.e mobile phone or tablet (actually for which devices I need the collapsible navbar), the button appears but I'm not able to open the navbar. This should not happen. If I click on the navbar button (three line button) nothing happens.

            <button type="button"  data-toggle="collapse" data-target="#collapsable-nav" aria-expanded="false">
              <span >Toggle navigation</span>
              <span ></span>
              <span ></span>
              <span ></span>
            </button> 
          </div>

          <div id="collapsable-nav" >
            <ul id="nav-list" >
              <li>
                <a href="menu-categories.html">
                  <span ></span>
                  <br >Menu
                </a>
              </li>
              <li>
                <a href="#">
                  <span ></span>
                  <br >About
                </a>
              </li>
              <li>
                <a href="#">
                  <span ></span>
                  <br >Awards
                </a>
              </li>
              <li id="phone" >
                <a href="tel:410-602-5008">
                  <span>410-602-5008</span>
                </a>
                <div>* We Deliver</div>
              </li>
            </ul>
          </div>
