# ASP.NET Core CheckBoxGroup Overview

The Telerik UI CheckBoxGroup TagHelper and HtmlHelper for ASP.NET Core are server-side wrappers for the Kendo UI CheckBoxGroup widget.

The CheckBoxGroup allows to style and provide checkbox functionality to list elements, set the position of the labels, attributes and custom css classes.

## Initializing the CheckBoxGroup

The following example demonstrates how to define the CheckBoxGroup.

```Razor HtmlHelper
    @(Html.Kendo().CheckBoxGroup()
        .Name("checkboxgroup")
    )
```

```Razor TagHelper
     <kendo-checkboxgroup name="checkboxgroup"
            input-name="checkboxItem">
    </kendo-checkboxgroup>
```

## Basic Configuration

The following example demonstrates the basic configuration for the CheckBoxGroup.

```Razor HtmlHelper
    @(Html.Kendo().CheckBoxGroup()
        .Name("checkboxgroup")
        .Items(i =>
        {
            i.Add().Label("Spain").Value("1");
            i.Add().Label("Italy").Value("2");
            i.Add().Label("UK").Value("3");
        })
        .Value(new string[] { "1" })
    )
    <script>
    $(function() {
        // The Name() of the CheckBoxGroup is used to get its client-side instance.
        var checkboxgroup = $("#checkboxgroup").data("kendoCheckBoxGroup");
    });
    </script>
```

```Razor TagHelper
    @{
        var data = new string[]{ "1" };
    }
    <kendo-checkboxgroup name="checkboxgroup"
                        value="data" >
        <kendo-checkboxgroup-items>
            <kendo-checkboxgroup-item value="1" label="Spain"></kendo-checkboxgroup-item>
            <kendo-checkboxgroup-item value="2" label="Italy"></kendo-checkboxgroup-item>
            <kendo-checkboxgroup-item value="3" label="UK"></kendo-checkboxgroup-item>
        </kendo-checkboxgroup-items>
    </kendo-checkboxgroup>
```
