自動對焦
如果你需要在開啟選單時,可以自動對焦在內部的連結或表單元件,並鎖定焦點在內部的話,可以使用 Headless UI 的 <FocusTrap>
元件 (雖然沒有紀錄在 Headless UI 的文檔中):
html
<template>
<Popover>
<Float :offset="4">
<PopoverButton class="px-3 py-1.5 flex justify-center items-center bg-rose-50 hover:bg-rose-100 text-rose-500 rounded">
Button
</PopoverButton>
<PopoverPanel class="w-[240px] h-[70px] p-3 bg-white text-rose-500 border border-gray-200 rounded-md shadow-lg focus:outline-none">
<FocusTrap>
<button type="button" class="focus:ring">link 1</button>
<button type="button" class="focus:ring">link 2</button>
</FocusTrap>
</PopoverPanel>
</Float>
</Popover>
</template>
<script setup>
import {
FocusTrap,
Popover, PopoverButton, PopoverPanel,
