bootstrap 4滑块旋转木马多旋转木马内部

Question

当我单击幻灯片3的菜单时，如何按组同时制作所有旋转木马内部幻灯片？

我尝试使用自举轮播来同时控制所有项目幻灯片，但我发现它对我不起作用。有人知道吗？

 <div id="myCarousel" class="carousel slide" data-ride="carousel">
    <!-- Carousel indicators -->
    <ol class="carousel-indicators">
        <li data-target="#myCarousel" data-slide-to="1">slide 2</li>
        <li data-target="#myCarousel" data-slide-to="2">slide 3</li>
    </ol>
    <!-- Wrapper for carousel items -->

    <div class="carousel-inner">
        <div class="carousel-item active">
            <img src="images/slide4.png">
        </div>
        <div class="carousel-item">

        <div class="carousel-item">
            <img src="images/slide6.png">
        </div>
    </div>

    <div class="carousel-inner">
        <div class="carousel-item active">

        <div class="carousel-item">
