# Usage

Use ManuBuilder to create a Menu with MenuItems, and then call Menu.popup_at() to show Menu.  
When a MenuItem is clicked, SelectedMenuItem data is returned.

```rust
fn example(hwnd: HWND) {
    let mut builder = MenuBuilder::new(hwnd);

    builder.check("menu_item1", "Fit To Window", "", true, None);
    builder.separator();
    builder.text_with_accelerator("menu_item2", "Playlist", None, "Ctrl+P");
    builder.text_with_accelerator("menu_item3", "Toggle Fullscreen", None, "F11");
    builder.text("menu_item4", "Picture In Picture", None);
    builder.separator();
    builder.text_with_accelerator("menu_item5", "Capture", None, "Ctrl+S");
    builder.separator();

    let mut submenu = builder.submenu("Theme", None);
    submenu.radio("submenu_item1", "Light", "Light", "Theme", true, None);
    submenu.radio("submenu_item2", "Dark", "Dark", "Theme", false, None);
    submenu.build().unwrap();

    let menu = builder.build().unwrap();

    let selected_item = menu.popup_at(100, 100);
}
```
WebView2 may receive all keyboard input instead of its parent window([#1703](https://github.com/MicrosoftEdge/WebView2Feedback/issues/1703)).    
Using WebView2, you may need to enable the feature flag.
```
--enable-features=msWebView2BrowserHitTransparent
```

## Accelerator

Accelerators are used only to display available shortcut keys by default.  
Use "accelerator" feature to treat accelerators as commands.  
With this feature, when a shortcut key is pressed, the corresponding MenuItem is returned as the result of Menu.popup_at().  

```rust
features = ["accelerator"]
```
