This time I will bring you Jquery HTML CSS to implement the drop-down list function. What are the precautions for Jquery HTML CSS to implement the drop-down list function? The following is a practical case. Let’s take a look. 

<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>fruit</title>
<style type="text/css">
.hide {
 display: none;
}
p {
 float: left;
 width: 100%;
}
.selector-containter {
 margin-bottom: 10px;
}
.selector {
 width: 200px;
 background: #FFF;
 border: 1px solid #DDD;
}
.selector-hint {
 width: 178px;
 border: 1px solid #DDD;
}
.selector-expand {
 width: 8px;
 border: 1px solid #DDD;
}
.selector-collapse {
 width: 8px;
 border: 1px solid #DDD;
}
</style>
<script src="jquery-3.2.1.min.js"></script>
<script>
$(document).ready(function() {
  //使用on方法，采用事件委派机制，selector-option-container中的内容为后续动态追加
  $('.selector').on('click', '.selector-expand', function() {
    $(this).parent().children('.selector-option-container').children().remove();
    $(this).parent().children('.selector-option-container').append('<p><input type="checkbox" name="fruitGroup" class="selector-checkbox"/></p><p class="selector-option">apricot</p>');
    $(this).parent().children('.selector-option-container').append('<p><input type="checkbox" name="fruitGroup" class="selector-checkbox"/></p><p class="selector-option">banana</p>');
    $(this).nextAll('.selector-option-container').removeClass('hide');
  });
  $('.selector').on('click', '.selector-collapse', function() {
    $(this).nextAll('.selector-option-container').addClass('hide');
  });
  $('.selector-t1').on('click', '.selector-option', function() {
    $(this).parent().parent().children('.selector-hint').text($(this).text());
    $(this).parent().addClass('hide');
  });
  $('.selector-t1').on('click', '.selector-checkbox', function() {
    $(this).parent().parent().parent().children('.selector-hint').text($(this).parent().next().text());
    //采用prop方法，对于值为布尔型的属性赋值
    $(this).prop('checked', false);
    $(this).parent().parent().addClass('hide');
  });
});
</script>
</head>
<body>
<p id="titan" class="selector-containter">
<p id="fruit">
 <p class="selector">
  <p class="selector-hint">select fruit</p>
  <p class="selector-expand">+</p>
  <p class="selector-collapse">-</p>
  <p class="selector-option-container">
  </p>
 </p>
</p>
</p>
<p id="athena" class="selector-t1 selector-containter">
<p id="fruit">
 <p class="selector">
  <p class="selector-hint">select fruit</p>
  <p class="selector-expand">+</p>
  <p class="selector-collapse">-</p>
  <p class="selector-option-container">
  </p>
 </p>
</p>
</p>
</body>
</html>
