Checkboxes are very simple input widgets: an empty square that can be checked or not. They permit the user to make a binary choice.
<b:selectBooleanCheckbox> makes the Bootstrap style of displaying checkboxes available to JSF programmers.
Use the caption attribute to display the label checkbox. Don't confuse it with the label attribute. This puts the label above the checkbox, as you can see in the next example.
disabled attribute.readonly is not supported yet. You can simulate it by adding onclick="return false;".
However, this doesn't prevent the user from toggling the checkbox via their keyboard. More precisely, it depends on your browser - some browsers
suppress the keyboard if there's onclick="return false;", but it's not guaranteed to work with every browser.
The example below shows both options:
The example below shows both options:
Bootstrap 3 doesn't support languages writing from right to left properly. Hence BootsFaces offers limited support of RTL, too. However, you can add RTL by adding this library:

The example shows the out-of-the-box support of BootsFaces:
The <b:selectBooleanCheckbox > supports the full suite of JavaScript and AJAX events,
as described in the description of AJAX in BootsFaces. Basically, each of the
many JavaScript callback handlers (the on[event] attributes) also supports AJAX.
To get familiar with BootsFaces AJAX, try the
BootsFaces AJAX demo project.
If the field has a FacesMessage, one of the CSS classes bf-info, bf-warning,
bf-error or bf-fatal is added to the label, depending on which error severity the message has.
The latter two classes color the label red. bf-warning colors it orange. You can override this default setting in a custom CSS file.
If there's no message,
the field and its label bear the pseudo CSS class bf-no-message and has-success. The latter colors the label green by default.
required attribute since 0.8.5The required attribute works a bit different than the required attribute
of other input fields. You can't leave a checkbox empty. Even if you don't check it, this may be
a deliberate decision. As a consequence, most JSF frameworks ignore the required
attribute. However, since version 0.8.5 setting the required attribute amount to
forcing the user to check it. A typical usecase is accepting the EULA of your application.
You can use all the attributes controlling the responsive behaviour of <b:column />
also with <b:selectBooleanCheckbox />. The example may look a bit odd, because checkboxes
don't fill all the available screen space, but still, it shows the idea nicely:
You can play also with col-*-*, visible and hidden attribute, as any bootstrap elements. For example:
| Attribute | Default value | Description |
|---|---|---|
| accesskey | (none) | Access key to transfer focus to the input element. |
| ajax | false | Whether the Button submits the form with AJAX. |
| alt | (none) | Alternate textual description of the input element. |

false | Setting this flag updates the widget on every AJAX request. |

| display | block | If you use the "visible" attribute, the value of this attribute is added. Legal values: block, inline, inline-block. Default: block. |
| escape | true | By default, the caption and the tooltip encode HTML and JavaScript code. Instead of being executed, the source code is displayed. This protects you against hacker attacks. By setting escape=false, you deactivate the protection, and allow HTML and JavaScript code to be rendered. |
