+# Checkbox
+The checkbox class replaces a value from the results with an default html checkbox.
+
+[Go back to fields](https://singlequote.github.io/Laravel-datatables/fields)
+
+### Default checkbox
+Below is an example on how to generate a default html input with type checkbox.
+
+```php
+Checkbox::make('email_verified_at')
+```
+The checkbox field can be extended with a lot of available methods. Such as classes and routes. 
+
+#### Class
+Add dom classes to the checkbox
+
+```php
+Checkbox::make('email_verified_at')->class('my-custom-checkbox')
+// <input type="checkbox" class="my-custom-checkbox"/>
+```
+
+#### Icon
+Add an icon before the checkbox
+
+```php
+Checkbox::make('email_verified_at')->icon('material-icons', optional 'edit'),
+// <i class="material-icons">edit</i> <input type="checkbox" />
+
+Checkbox::make('email_verified_at')->icon('fa fa-edit'),
+// <i class="fa fa-edit"></i> <input type="checkbox" />
+```
+
+#### Checked
+The checkbox can set to checked when passing a value that is not null, false or int 0.
+
+```php
+Checkbox::make('email_verified_at')->checked(true)
+// <input type="checkbox" checked="checked"/>
+Checkbox::make('email_verified_at')->checked('deleted_at') //when value is null => false,
+// <input type="checkbox" />
+```
+
+
+### Add onclick
+The onclick method can be used to trigger an event.
+
+```php
+Checkbox::make('email_verified_at')->onclick("$('form').submit()"),
+
+// <input type="checkbox" onclick="$('form').submit()"/>
+```
+
+### Full example
+```php
+Checkbox::make('email_verified_at')->class('my-checkbox')->checked('email_verified_at !== null')->name('email_verified_at')->data(['user_id' => 'id'])->onclick("updateEmailVerifiedAt(this)"),
+
+```
+
+```html
+<input type="checkbox" onclick="updateEmailVerifiedAt(this)" class="my-checkbox" checked="checked" name="email_verified_at" data-user="1" />
+```
