`examples/storybook/stories.zig:2463`

```zig
// ── DatePicker ──
pub fn buildDatePicker(scope: *ui.Scope, cx: *ui.Cx) anyerror!*ui.Node {
    const dp = try W.DatePicker(.{ .placeholder = "Pick a date", .initial_year = 2026, .initial_month = 5 }).mount(scope, cx);
    return dp.wrapper;
}
```

[在 GitHub 查看源码examples/storybook/stories.zig:2463](https://github.com/version-next/zenit/blob/HEAD/examples/storybook/stories.zig#L2463)

这是 Storybook 中该 story 的原样代码（zenit 5f9add5+wip 2026-09-30）。其中 `W` 即 `ui.widgets`，`col` / `row` / `label` 是 Storybook 内的布局小工具。
