Bootstrap 4 changement de curseur en cliquant sur la liste déroulante

À l’aide de Bootstrap 4, j’essaie de créer un menu déroulant avec caret (ex: pointant vers la droite). En cliquant sur le menu déroulant, la direction du point d'insertion du curseur devrait être modifiée (Ex: en bas).

J'ai un moyen de le faire

/*Please refer the above link for full code details*/

<a class="accordion-toggle" data-toggle="collapse" data-parent="#accordion" href="#collapseOne">
          Collapsible Group Item #1
</a>

<div id="collapseOne" class="panel-collapse collapse in">
      <div class="panel-body">
        This content is hidden
      </div>
</div>

.css

.panel-heading .accordion-toggle:after {
    font-family: 'Glyphicons Halflings';
    content: "\e114";
    float: right;
    color: grey;
}
.panel-heading .accordion-toggle.collapsed:after {
    content: "\e080";
}

Mais le problème, c’est d’abord tous les caractères pointés vers le bas qui devraient être corrects

Il y a d'autres approches . Mais je ne veux pas utiliser JQuery car mon application est angulaire 4. Voudrais éviter JQuery/JS autant que possible.

Ce n'est pas un dupliquer question.

Merci d'avance...

Dans Bootstrap V4, ils ont abandonné les Glyphicons. Le code ci-dessous fonctionnera bien selon vos besoins .. Pour le style d'icône déroulant, vous pouvez utiliser une police de caractères géniale.

[data-toggle="collapse"]:after {
display: inline-block;
    display: inline-block;
    font: normal normal normal 14px/1 FontAwesome;
    font-size: inherit;
    text-rendering: auto;
    -webkit-font-smoothing: antialiased;
    -moz-osx-font-smoothing: grayscale;
  content: "\f054";
  transform: rotate(90deg) ;
  transition: all linear 0.25s;
  }   
[data-toggle="collapse"].collapsed:after {
  transform: rotate(0deg) ;
}

Voici comment j'ai obtenu cela fonctionne avec Bootstrap4-CSS-fontAwesome & No JS/JQuery.

<a class="accordion-toggle collapsed" data-toggle="collapse" href="#anyId">
  click
</a>

<div id="anyId" class="collapse">
    Hi
</div>

.css

.accordion-toggle:after {
  font-family: 'FontAwesome';/* essential to enable caret symbol*/
  content: "\f0d7";/* adjust as needed, taken from font-awesome.css */
  color: grey;
}
.accordion-toggle.collapsed:after {
  /* symbol for "collapsed" panels */
  content: "\f0da";  /* adjust as needed, taken from font-awesome.css */
}

Si vous utilisez SCSS, il existe des mixins intégrés spécialement conçus pour cela, situés à ~bootstrap/scss/mixins/_caret.scss.

caret-down, caret-up, caret-right, caret-left et caret($direction).

Donc, cela peut devenir aussi simple que:

.panel-heading .accordion-toggle {
    @include caret(right);

    &.collapsed {
        @include caret(left);
    }
}

ou, si votre code HTML contient l'attribut aria-expanded (ce qui est vivement conseillé)

.panel-heading .accordion-toggle {
    &[aria-expanded="false"] {
        @include caret(left);
    }

    &[aria-expanded="true"] {
        @include caret(right);
    }
}

Voici comment j'ai fait fonctionner le mien en utilisant uniquement CSS pour bootstrap 4.2 et fontawesome. J'ai utilisé le label aria et ajouté des transitions pour l'icône, en utilisant une classe span pour l'icône

CSS:

#accordionExample .btn[aria-expanded=false] span:before {
  font-family: "Font Awesome 5 Free";
  font-weight: 900;
  content: "\f107";
  float: right;
 transition: all .5s;
}

#accordionExample .btn[aria-expanded=true] span:before {
  font-family: "Font Awesome 5 Free";
  font-weight: 900;
  content: "\f107";
  float: right;
  transition: all .5s;
  -webkit-transform: rotate(180deg);
    -moz-transform: rotate(180deg);
    transform: rotate(180deg);
}

HTML:

<div class="container my-5 mw-600">
  <div class="accordion" id="accordionExample">
  <div class="card">
    <div class="card-header" id="headingOne">

        <a class="btn btn-link d-flex" data-toggle="collapse" data-target="#collapseOne" aria-expanded="false">
          Collapsible Group Item #1
          <span class="ml-auto"></span></a>

    </div>

    <div id="collapseOne" class="collapse" aria-labelledby="headingOne" data-parent="#accordionExample">
      <div class="card-body">
