自定义选择阴影在选择选项后不隐藏 - 仅限 Safari

Question

我有这个自定义选择，当它打开其选项列表时，上面有一个阴影，但是当我选择一个选项并且列表关闭时，阴影没有隐藏。此问题仅在 Safari 上发生。下面是一个示例：

编辑：仅当页面上有另一个输入字段时，才会发生此问题。

(function($) {

if ($dropdown.length) {
$dropdown.remove();
create_nice_select($select);
if (open) {
$select.next().trigger('click');
} else if (focused) {
$select.parents('.form-group-select').toggleClass('focused');
}
}
});

Answer 1

Safari 中似乎有一个错误。 通过摆弄，我发现如果我删除

overflow: hidden;

从您的 CSS 类".nice-select"中，它似乎有效。

请尝试一下。

编辑： 尝试添加

display: none;

到 ".nice-select .list" 和

display: block;

到 ".nice-select.open .list">
