Dabeecadaha ka jawaaba

Navbars waxay isticmaali karaan .navbar-toggler, .navbar-collapse, iyo .navbar-expand{-sm|-md|-lg|-xl|-xxl}fasallo si ay u go'aamiyaan marka nuxurkoodu ku dumo badhan gadaashiisa. Marka lagu daro tas-hiilaadka kale, waxaad si fudud u dooran kartaa marka aad muujinayso ama qarinayso waxyaabo gaar ah.

Navbars aan waligood dumin, ku dar .navbar-expandfasalka navbar-ka. Navbar-yada had iyo jeer burbura, ha ku darin wax .navbar-expandfasal ah.

Toggler

Togglers Navbar si toos ah ayay bidix u toosan yihiin, laakiin haddii ay raacaan walxaha walaalaha ah sida a .navbar-brand, waxay si toos ah ula toosi doonaan midigta fog. Dib u noqoshada calaamadayntaada waxay beddeli doontaa meelaynta toggler-ka. Hoos waxaa ah tusaalayaal qaababka beddelka ee kala duwan.

Iyadoo aan .navbar-brandlagu tusin meesha ugu yar:

html 
<nav class="navbar navbar-expand-lg bg-light">
  <div class="container-fluid">
    <button class="navbar-toggler" type="button" data-bs-toggle="collapse" data-bs-target="#navbarTogglerDemo01" aria-controls="navbarTogglerDemo01" aria-expanded="false" aria-label="Toggle navigation">

    </button>
    <div class="collapse navbar-collapse" id="navbarTogglerDemo01">
      <a class="navbar-brand" href="#">Hidden brand</a>
      <ul class="navbar-nav me-auto mb-2 mb-lg-0">
        <li class="nav-item">

        </li>
        <li class="nav-item">

Waxyaabaha dibadda

Mararka qaarkood waxaad rabtaa inaad isticmaasho plugin burburka si aad u kiciso curiyaha weelka ee nuxurka qaab ahaan u fadhiya meel ka baxsan .navbar. Sababtoo ah pluginkeena wuxuu ka shaqeeyaa isku id- data-bs-targetdhafka, taas si fudud ayaa loo sameeyaa!

html 
<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">

      <span class="navbar-toggler-icon"></span>
    </button>
  </div>
</nav>

Markaad tan sameyso, waxaan kugula talineynaa inaad ku darto JavaScript dheeraad ah si aad barnaamij ahaan diirada ugu wareejiso weelka marka la furo. Haddii kale, isticmaalayaasha kiiboodhka iyo isticmaalayaasha tignoolajiyada caawinta waxay u badan tahay inay ku adkaan doonto helista waxa cusub ee la daaha ka qaaday - gaar ahaan haddii weelka la furay uu ka hor yimaado beddelaha qaab dhismeedka dukumeentiga. Waxaan sidoo kale ku talinaynaa in la hubiyo in toggler-ku uu leeyahay sifada aria-controls, iyadoo tilmaamaysa idweelka ka kooban yahay. Aragti ahaan, tani waxay u oggolaanaysaa isticmaalayaasha tignoolajiyada caawinta inay si toos ah uga boodaan toggler-ka oo ay u gudbaan weelka ay gacanta ku hayso-laakin taageerada tani hadda aad bay u yar tahay.
