使语义UI搜索选择下拉滚动到点击选定的项目？

Question

我正在使用Semantic UI可搜索下拉菜单，如果您不熟悉它，可以在此处找到：http://semantic-ui.com/modules/dropdown.html#search-selection。

我该如何做到这一点，以便一旦在下拉菜单中选择了一个项目，当您点击并重新点击时，它会在列表顶部显示当前选定的项目？那么滚动到选定/活动项目？

Answer 1

您正在使用什么版本的语义UI？因为Semantic UI搜索选择下拉菜单的默认行为很好。

$('.ui.search.dropdown').dropdown();
