选择选项后，自定义选择阴影不会隐藏 - 仅限Safari

时间：2017-07-11 11:50:46

标签： javascript jquery html css safari

我有这个自定义选择，当它打开它的选项列表时会有一个阴影，但当我选择一个选项并且列表关闭时，阴影不会隐藏。此问题仅在Safari上发生。这是一个样本：

编辑：只有在页面上有其他输入字段时才会出现问题。

1 个答案:

答案 0 :(得分：2)

似乎Safari中存在一个错误。 通过摆弄我发现如果我删除

overflow: hidden;

来自CSS-class“.nice-select”，它似乎有效。

请试一试。

编辑： 尝试添加

display: none;

到“.nice-select .list” 和

display: block;

到“.nice-select.open .list”
