<script src="path/to/jquery.twbs-toggle-buttons.min.js"></script>

The Basics

<label class="control-label">Is it true?</label>
<div class="btn-group btn-group-toggle" data-toggle="buttons">
    <div class="btn active" role="button">
        <input type="radio" name="options" value="1" required="required">yes 1
    </div>
    <div class="btn active" role="button">
        <input type="radio" name="options" value="2">yes 2
    </div>
    <div class="btn" role="button">
        <input type="radio" name="options" value="0">no
    </div>
</div>
<script>
    $(".btn-group-toggle").twbsToggleButtons();
</script>

Options

twbsBtnSelector

default: '[role="button"]'

The default selector of all buttons is [role="button"]. To avoid this special html attribute you can change the option twbsBtnSelector, for instance to a class.

<label class="control-label">Is it true?</label>
<div class="btn-group btn-group-toggle">
    <div class="btn" required="required">yes</div>
    <div class="btn">no</div>
</div>
<script>
    $(".btn-group-toggle").twbsToggleButtons({
        twbsBtnSelector: ".btn"
    });
</script>

classActive

default: 'btn-success'

To detect an optical difference between active and inactive toggle buttons the two options classActive and classInactive are set to default bootstrap classes. Change the options and use other classes to make a difference between both toggle states.

Hint: Use an array of classes to set multiple classes.

$(".btn-group-toggle").twbsToggleButtons({
    classActive: "my-active-button",
    classInactive: ["my-inactive-button-1", "my-inactive-button-2"]
});

classInactive

default: 'btn-secondary'

See classActive

Events

To avoid problems with the order of executing click events on the twbs-toggle-buttons you can use two event types to handle events.

Click Event

The click event is fired on the button.

❗ Be careful to get the right state of the button! To get the state after button toggling use event twbsToggleButtons:activate Event.

$(".btn-group-toggle").find("[role='button']").on("click", function (e)
{
    console.log(e);
});

twbsToggleButtons:activate Event

This event is fired after the state of the button getting activated was changed.

$(".btn-group-toggle").find("[role='button']").on("twbsToggleButtons:activate", function (e)
{
    console.log(e);
});

Tricks and Tips

Checkboxes or Radio Buttons

<label class="control-label">Choose your documents!</label>
<div class="btn-group btn-group-toggle" data-toggle="buttons">
    <div class="btn active" role="button">
        <input type="checkbox" name="options[]" value="1">Document 1
    </div>
    <div class="btn active" role="button">
        <input type="checkbox" name="options[]" value="2">Document 2
    </div>
    <div class="btn" role="button">
        <input type="checkbox" name="options[]" value="3">Document 3
    </div>
</div>

Required Radio Group

If radio buttons are used, usually exactly one button must be active.

To allow a button group without any active button, dismiss the attribute required in the input fields.

Overwrite classActive

Sometimes it is useful to change the active class of single toggle button. To do so, add the tml data attribute data-twbs-toggle-buttons-class-active with a corresponding class.

<label class="control-label">Is it true?</label>
<div class="btn-group btn-group-toggle" data-toggle="buttons">
    <div class="btn active" role="button">
        <input type="radio" name="options" value="1" required="required">yes
    </label>
    <div class="btn active" role="button">
        <input type="radio" name="options" value="0" data-twbs-toggle-buttons-class-active="btn-danger">no
    </label>
</div>
