Introduction to Bootstrap Toggle Button

Toggle Button in Bootstrap is used for choosing any one choice from 2 toggle button choices. Toggle Button is also called a switch button. We can achieve the toggle button functionality by using <input type=”checkbox”>. It is used for activating one option from the two predefined options. We can say this button is for the on/off action button.

This toggle button is used most of the time with question-related forms.

Example: Do you have a disability? Yes/No. If we choose Yes then further we have to provide some more information like disability type, percentage of disability, period of disability, etc.

Because of these toggle buttons, we can reduce the form filling time by disabled the inapplicable options. Toggle Buttons Used Areas:

On/Off functionality
Forms
Preference choices

Why Bootstrap over HTML?

In HTML, developers must write each and every class, ids, links, buttons, cascading styles, etc..
Whereas in Bootstrap most of the predefined classes, links, and buttons, etc. with their own cascading styles to reduce code complexity.

Note: Bootstrap files are also saved with .html extension.

How does it work in Bootstrap?

Bootstrap Toggle Button worked based on <input type=”checkbox” class=” any bootstrap predefined class”>.

1. Default Toggle Button

Syntax:

<div class="custom-control custom-switch">
<input type="checkbox" class="custom-control-input">
<label class="custom-control-label" for="customSwitches">Any statement</label>
</div>

Explanation:

class=”custom-control custom-switch”> gives predefined bootstrap styles around checkbox button and gives default toggle button.
class=” custom-control-input” makes the checkbox as a custom control input button.
class=”custom-control-label” makes label with default styles.
for=”customSwitches” makes toggle button iterative.

2. Switch Button

<div class="switch">
<label>
Off
<input type="checkbox" checked>
<span class="lever"></span> On
</label>
</div>

class=”lever” makes button on/off functionality.

3. Default Toggle Button with Disabled Attribute

<div class="custom-control custom-switch">
<input type="checkbox" class="custom-control-input" disabled=”disbaled”>
<label class="custom-control-label" for="customSwitches">Any statement</label>
