如何解决Bootstrap 4.5和Bootstrap-Select
以下是重现我的问题的示例HTML文件。第一个下拉菜单根据需要在屏幕上呈现，但有一个例外。当我添加data-mobile="true"属性时，实时搜索框消失。当不包含data-mobile="true"时，将显示实时搜索，但文本会流到屏幕左侧。为dropright使用类无助于解决该问题，并且看来data-mobile="true"对于使下拉菜单中的文本完全显示在屏幕上而不被截断很有用。
但是，第二个下拉列表是多选的，这是我看到的第二个问题。如果不包含data-mobile="true"（例如<select multiple class="form-control selectpicker" data-live-search="true">），则该框为多选框，具有实时搜索功能，但文本不在屏幕上显示。但是，当我添加data-mobile="true"时，该框将根本不再显示或用作多选。
似乎我缺少有关如何正确使用data-mobile="true"的知识。要么就是该数据属性与我正在使用的其他属性存在错误/冲突。我尝试按照https://developer.snapappointments.com/bootstrap-select/methods/的建议添加以下内容，但没有成功
<script>
$(document).ready(function () {
$('.selectpicker').selectpicker('mobile');
})
</script>
任何人都可以提出一个解决方案，以使我的多选框显示在右侧（如第一个下拉列表中所示），然后还具有实时搜索功能吗？
