# TagInput

```gistui
root = Form("share", TagInput("emails", "Share with", type:email, placeholder:"Type an email and press Enter", value:["ada@example.com"], required))
```

This is the line a model reads in the system prompt.

```gistui
TagInput(name, label, options:[str], value:[str], type:text|email|url, placeholder:str, min:num, max:num, error:str, bind:$var, size:Size, hint:str, required)
```

- **Group:** Forms
- **Children:** No
- **Positional arguments:** `name`, `label` (a trailing `?` means it may be left out)
