add filtering buttons in updatemenus

Currently its possible to update the plots with updatemenus either using dropdown or buttons

In usecases where there are many groups to analyse, it is impractical to scroll through them and the buttons are out of view when its dropdown is not used. A way to filter the dropdown list based on text input would be extremely useful.

Thank you very much, really hoping to see some feature/alternative workaround to make this possible.

Out-of-view buttons

Scrolling dropdown

该 issue 提到了 updatemenus、下拉菜单和按钮，但没有指出文件、测试或入口点。首先定位 updatemenus 的实现及其相关的交互式 plot 测试，然后确定文本过滤应放在哪里。当用户可以通过输入来筛选大型下拉菜单，同时仍能获得可用的 plot 更新，并且相关行为有测试覆盖时，即视为完成。
