}Expand description
Props for the Menu component.
图标按钮触发的操作菜单。
- 打开后焦点落在第一个可用项;↑/↓ 在可用项间循环(roving focus),Home/End 跳首尾;
- Enter/Space 选中并关闭,Esc 关闭,关闭后焦点回到触发按钮;Tab 关闭并自然流转;
- 点菜单外部关闭;不可用项变淡、写明原因,键盘与点击都跳过。
触发器与菜单项的 id(menu-N-trigger 等)在挂载后由客户端计数分配:全局计数器在服务端是
进程级的,直接写进 SSR HTML 会与水合后的客户端计数不一致。
Props:
label:触发按钮的读屏名称与悬浮提示,如「更多操作」icon:触发按钮图标,缺省Ellipsisitems:菜单项(Vec<MenuItem>或返回它的闭包 / 信号)on_select:选中某项时回传其idplacement:"bottom"(默认)/"top";align:"end"(默认,右对齐)/"start"

impl MenuProps
Sourcepub fn builder() -> MenuPropsBuilder<((), (), (), (), (), (), ())>
pub fn builder() -> MenuPropsBuilder<((), (), (), (), (), (), ())>
Create a builder for building MenuProps.
On the builder, call .label(...), .items(...), .on_select(...), .icon(...)(optional), .size(...)(optional), .placement(...)(optional), .align(...)(optional) to set the values of the fields.
Finally, call .build() to create the instance of MenuProps.
