el-dropdown改成鼠标右键触发下拉菜单

// handleChange鼠标右键才会触发
<div v-for="(item, index) in list" :key="index" @click.right.prevent="handleChange(item)">
	// 将trigger设置成manual，去掉默认触发拉下菜单的行为，添加ref
	<el-dropdown trigger="manual" :ref="`dropdown${item.id}`">
		<div class="tb-dropdown">
			<span>{{ item.code }}</span>
		</div>
		<el-dropdown-menu slot="dropdown" class="lang-select-dropdown">
			<el-dropdown-item command="0">黄金糕</el-dropdown-item>
			<el-dropdown-item command="1">狮子头</el-dropdown-item>
		</el-dropdown-menu>
	</el-dropdown>
</div>

	return {
