具有自动完成功能和类别的Wicket下拉菜单 [英] Wicket Dropdown with Autocomplete and Categories

问题描述

我需要一个带有下拉菜单的自动完成功能，其结果的分类类似于HTML select-带有键盘导航的optgroup.

I need an autocomplete with a dropdown with results categorised like in HTML select - optgroup with keyboard navigation.

我尝试基于以下方式实现带有组的检票选择组件:在Wicket中使用分隔符DropDownChoice (带有用于搜索的文本字段)，但不能通过向下箭头"跳转到该选项.

I tried to implement a wicket Select component with groups based on this: Separator in a Wicket DropDownChoice with a textfield for search, but can't jump to select with "Arrow down".

还有其他想法吗?
