Introduction to Checkbox in Bootstrap
Bootstrap used many buttons with one click, but sometimes we need to choose an option. Choosing an option has two ways one is a radio button, and another is a checkbox. The radio button has only one option to choose from others. In any condition, we need to choose more than one option that is the time checkbox working. Checkbox has multiple options to choose from the many options. The checkbox is used to choose options in multiple choices with a click on the checkbox. The use of checkbox buttons is multiple choice questions in the exam when the question has multiple answers to one question. Bootstrap has own class of checkbox button, you will see below.

Checkbox Using Buttons
Checkbox in bootstrap also worked out with the buttons with some classes to look more stylish and elegant in form. Class button-group-toggle, button class has to used in < div > and < label > respectively. With the button-group-toggle class, data-toggle=’buttons’ class also necessary in the form. In the < input >, the type must be a checkbox for working as the checkbox. Let’s see some examples to understand more about toggle in checkbox using bootstrap.
Code:
<!DOCTYPE html>
<html >
<head>
<title>Bootstrap Example checkbox</title>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1">
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.4.0/css/bootstrap.min.css">
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.4.1/jquery.min.js"></script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.4.0/js/bootstrap.min.js"></script>
</head>
<body>
<div class="container">
<form>
<label > Languages </label>
<div class="btn-group-toggle" data-toggle = "buttons">
<label class="btn btn-primary ">
<input type="checkbox" checked autocomplete = "off"> HTML
</label>
<label class="btn btn-primary">
<input type="checkbox" checked autocomplete = "off"> CSS
</label>
<label class="btn btn-primary">
<input type="checkbox" checked autocomplete = "off"> JavaScript
</label>
<label class="btn btn-primary">
<input type="checkbox" checked autocomplete = "off"> Bootstrap
</label>
</div>
</form>
</div>
</body>
</html>Output:
Description:
- For this example, we used the primary button but any button can be used to checkout but ‘autocomplete’ must be off to not save extra data.
- If the user presses on the button then it is automatically chosen as an option and in the toggle button, the user can choose more options just clicking on buttons.
- Here we have four options to choose the languages, users can choose multiple languages.
- class=’btn-group-toggle’ is used for style the input of the form.
- Because this data-toggle, JavaScript allows Toggling to the buttons so Active and not active mode can be interpreted.
Using the Active Button of Checkbox in Bootstrap
If the user active class adds in button then this button automatically is checked and users have remaining options to choose. This button changes the color to get the activated sign.
Let’s see the following example:
Code:
<div class="container">
<form>
<label > Languages </label>
<div class="btn-group-toggle"data-toggle= "buttons">
<label class="btn btn-primary active ">
<input type="checkbox" checked autocomplete = "off"> HTML
</label>
<label class="btn btn-primary">
<input type="checkbox" checked autocomplete = "off"> CSS
</label>
<label class="btn btn-primary">
<input type="checkbox" checked autocomplete = "off"> JavaScript
</label>
<label class="btn btn-primary">
<input type="checkbox" checked autocomplete = "off"> Bootstrap
</label>
</div>
</form>
</div>Output:
Description:
- This example can recognize the HTML button darker than others, which means this button is already active.
- On the < label> of HTML, add the active class with the primary button.
- This example also needs button-toggle = “buttons” instead of a button, because of the group of the button.
