如何只允许"checking"一个复选框

Question

如何编辑此代码笔以允许只检查一项，如果检查了另一项，则取消选中前一项，并使用自定义图像进行检查，而不是自动生成当前检查？

<!-- Example Dropdown -->
<div class="dropdown">
<button type="button" class="btn btn-secondary dropdown-toggle" data-toggle="dropdown">Menu</button>
<div class="dropdown-menu">
<a href="#" class="dropdown-item">Item 1</a>
<a href="#" class="dropdown-item dropdown-item-checked">Item 2</a>
<a href="#" class="dropdown-item">Item 3</a>
</div>
</div>
<p class="mt-4">

.dropdown-item-checked::before {
position: absolute;
left: .4rem;
content: '✓';
font-weight: 600;
}
body {
padding: 1rem;
}
// Toggle checkmarks
$(document).on('click', '.dropdown-item', function(event) {
event.preventDefault();
$(this).toggleClass('dropdown-item-checked');  
});

我不明白为什么隐藏单选按钮会有问题(我不是指可访问性，我只是指你想要实现的目标(。

这就是你想要的吗？

[name=items] {
display: none;
}
label {
display: block;
padding-left: 1rem;
}
:checked + label::before {
position: absolute;
left: .4rem;
content: '✓';
font-weight: 600;
}

<input type="radio" name="items" id="item-1">
<label for="item-1">Item 1</label>
<input type="radio" name="items" id="item-2" checked>
<label for="item-2">Item 2</label>
<input type="radio" name="items" id="item-3">
<label for="item-3">Item 3</label>
