# TagsInput

`ui.widgets.TagsInput`

Enter many tokens from the keyboard.

[Video](https://ui.surf/zenit/media/stories/tags.mp4?v=85989d0ec2)

**BEHAVIOR CONTRACT**

Comma / Enter commit, delete, focus and list updates all land on grapheme-safe boundaries.

**RECORDED INTERACTION**

The harness types “docs,” and it commits as a new tag.

`examples/storybook/stories.zig:3042`

```zig
// ── TagsInput ──
pub fn buildTagsInput(scope: *ui.Scope, cx: *ui.Cx) anyerror!*ui.Node {
    const a = cx.allocator;
    const c = try col(cx, 12);
    const ti = try ui.widgets.TagsInput(.{
        .initial_tags = &.{ "zig", "metal" },
        .width = 380,
    }, scope, cx);
    ti.input.meta.ownership.meta.test_id = "story.tags.input";
    ti.wrapper.meta.ownership.meta.test_id = "story.tags.wrapper";
    try c.appendChild(a, ti.wrapper);
    try c.appendChild(a, try label(cx, "End with comma (or click Add) to commit a tag."));
    return c;
}
```
