Question

im试图解决这个问题，我使用foreach php从Mysqli数据库中获取行，并在此处使用MaterializeCSS在容器im中显示为可折叠对象。

前3行将在容器中显示，而后3行将退出容器。

这是PHP和HTML代码：

<div class="container" style="margin-top:25px;">

<div class="postOffer right-align">
    <button class="btn waves-effect waves-light addOfferBtn" style="background-image: linear-gradient(90deg,#5c258d 0,#4389a2);">Add Recurring Offer </button>
    <div class="Offers center-align">

<?php
  $counter = 0;
    foreach ($u->fetchOffers($_SESSION['user']) as $row) {
        echo '<div class="createdOffers">
        <ul class="collapsible">';
        if($counter == 0){
          echo '<li class="active">
            <div class="collapsible-header active offerTitleCollapsible" data-id="'.$row['id'].'" style="font-weight: 900;">'.$row['offerTitle'].'<i class="material-icons" style="left: 0;">add</i></div>';
          }else{
            echo'<li>
            <div class="collapsible-header offerTitleCollapsible" data-id="'.$row['id'].'" style="font-weight: 900;">'.$row['offerTitle'].'<i class="material-icons" style="left: 0;">add</i></div>';
          }

这肯定是一个标记问题。 foreach应该在<li>而不是<ul>上运行。从if条件中取出初始<li>，以确保<div>标签在for循环的末尾有其结束标签，而不是在没有结束<li>的情况下结束for循环标签。我还在标记中添加了一些<div>标签。

<div class="container" style="margin-top:25px;">
