Me te takahuri kei te taha maui me te ingoa waitohu kei te taha matau:

    <a class="navbar-brand" href="#">Navbar</a>

Ihirangi o waho

I etahi wa ka hiahia koe ki te whakamahi i te mono tiango hei whakaoho i tetahi huānga ipu mo nga ihirangi e noho ana ki waho o te .navbar. Na te mea e mahi ana ta maatau mono i runga i te idme data-bs-targette taurite, he ngawari te mahi!

Collapsed content

Toggleable via the navbar brand.

<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>

Ina mahi koe i tenei, ka tūtohu kia whakaurua etahi atu JavaScript hei nuku i te arotahi ki te ipu ina whakatuwheratia. Ki te kore, ka uaua nga kaiwhakamahi papapātuhi me nga kaiwhakamahi hangarau awhina ki te rapu i nga ihirangi hou - ina koa ka tae mai te ipu i whakatuwherahia ki mua i te takahuri i te hanganga o te tuhinga. Ka tūtohu ano matou kia mohio kei te takahuri te aria-controlshuanga, tohu ki te ido te ipu ihirangi. I roto i te ariā, ma tenei ka taea e nga kaiwhakamahi hangarau awhina te peke tika mai i te takahuri ki te ipu e whakahaeretia ana e ia–engari ko te tautoko mo tenei he tino pahekeheke.
