### Checkbox and radio buttons
Bootstrap's `.button` styles can be applied to other elements, such as `<label>`s, to provide checkbox or radio style button toggling. Add `data-toggle="buttons"` to a `.btn-group` containing those modified buttons to enable toggling in their respective styles.
Bootstrap's `.button` styles can be applied to other elements, such as `<label>`s, to provide checkbox or radio style button toggling. Add `data-toggle="buttons"` to a `.btn-group` containing those modified buttons to enable their toggling behavior via JavaScript and add `.btn-group-toggle` to style the `<input>`s within your buttons.
The checked state for these buttons is **only updated via `click` event** on the button. If you use another method to update the input—e.g., with `<input type="reset">` or by manually applying the input's `checked` property—you'll need to toggle `.active` on the `<label>` manually.
Note that pre-checked buttons require you to manually add the `.active` class to the input's `<label>`.
{% example html %}
<div class="btn-group" data-toggle="buttons">
<div class="btn-group btn-group-toggle" data-toggle="buttons">
<label class="btn btn-secondary active">
<input type="checkbox" checked autocomplete="off"> Checkbox 1 (pre-checked)
</label>
