Ngokuguqula ngasekhohlo kunye negama lebhrendi ekunene:

Umxholo wangaphandle

Ngamanye amaxesha ufuna ukusebenzisa iplagin yokudilika ukuqalisa into yesikhongozeli somxholo ohleli ngaphandle kwe- .navbar. Kuba iplagin yethu isebenza idkwaye data-bs-targetihambelana, oko kwenziwa ngokulula!

<div class="collapse" id="navbarToggleExternalContent">
  <div class="bg-dark p-4">
    <h5 class="text-white h4">Collapsed content</h5>
    <span class="text-muted">Toggleable via the navbar brand.</span>
  </div>
</div>
<nav class="navbar navbar-dark bg-dark">
  <div class="container-fluid">
    <button class="navbar-toggler" type="button" data-bs-toggle="collapse" data-bs-target="#navbarToggleExternalContent" aria-controls="navbarToggleExternalContent" aria-expanded="false" aria-label="Toggle navigation">
      <span class="navbar-toggler-icon"></span>
    </button>
  </div>
</nav>

Xa usenza oku, sicebisa ukuquka iJavaScript eyongezelelweyo ukuhambisa ugxininiso ngokwenkqubo kwisikhongozeli xa sivulwa. Kungenjalo, abasebenzisi bebhodi yezitshixo kunye nabasebenzisi beetekhnoloji ezincedisayo baya kuba nobunzima bokufumana umxholo osanda kutyhilwa - ngakumbi ukuba isikhongozeli esivuliweyo siza phambi komguquli kwisakhiwo soxwebhu. Sikwacebisa ukuba uqinisekise ukuba umguquli uneempawu, ezikhomba kwisikhongozeli aria-controlssomxholo id. Ngokwethiyori, oku kuvumela abasebenzisi betekhnoloji abancedisayo ukuba batsibe ngokuthe ngqo ukusuka kwi-toggler ukuya kwisingxobo esisilawulayo-kodwa inkxaso yale nto okwangoku inqabile.
