Combobox (<b:selectOneMenu>)

Comboboxes give you a list of items to select from. As of Bootsfaces 0.6, comboboxes are not editable - they are pure drop-down menus.

<b:selectOneMenu> makes the Bootstrap style of displaying comboboxes available to JSF programmers.

Basic usage

Disabled items

Items can also be disabled. If so, they are grayed out, and they can't be selected.

A note on AJAX

Note that since BootsFaces 0.8.0, we favor an all-new approach to AJAX. The standard JSF approach to AJAX we used in the example above is supported by us, too, but we recommend to adopt the new BootsFaces style of AJAX (i.e. onclick="ajax:bean.method()"). Supporting standard JSF AJAX and the PrimeFaces approach to AJAX raises the complexity of the implementation considerably. So if you run into bugs with either the standard or the PrimeFaces syntax, bear with us, and report the bugs on our bug tracker.

Arrays and HashMaps broken in 0.8.5

The list of items can be defined as an <f:selectItems /> tag. BootsFaces uses a modified version of the algorithm PrimeFaces 5.1 uses to implement <f:selectItems />. As a result, you can use <b:selectOneMenu> almost the same way as <b:selectOneMenu>.

Due to a bug, arrays and hashmaps can be used to display the combobox, but the user input is not processed correctly by the server. This bug will be fixed in the next version of BootsFaces.

Labels as captions above the combobox

You can add a label to the combobox by jotting down the attribute label. This label is displayed above the combobox.

Prepending or appending facets since 0.8.5

To help you enhance the user experience, BootsFaces comes in with a useful feature:

You can easily prepend or append text to your InputTextareas and what you prepend and append will seem part of the input field.

To do so, you just need to use the facets prepend and append where you will place the h:outputText element (or any other element). Note that there's a minor layout glitch between the facet and the combobox (the rounded corner). You'll have to fix this with some CSS code.

You can even prepend and append at the same time, as in the following example:

Labels, required fields and error messages since 0.8.0

You can add a label by adding the attribute label. The label is also used by the JSF messages. To give you maximum flexibility, you can suppress automatic rendering of labels by adding renderLabel="false".

Required inputs fields and their labels both bear the CSS class bf-required. By default, this adds an asterisk to the label.

If the field has a FacesMessage, one of the CSS classes bf-info, bf-warning, bf-error or bf-fatal, depending on which error severity the message has. The latter two classes color the label red.

If there's no message, the field and its label bear the pseudo CSS class bf-no-message.

Non-AJAX:

AJAX and JavaScript since 0.8.0

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.


Responsive design since 0.9.0

You can use all the attributes controlling the responsive behaviour of <b:column /> also with <b:icon />:

Visibility depending on screen size since 0.8.6/0.9.0

You can play also with col-*-*, visible and hidden attribute, as any bootstrap elements. For example:


Visible on >= md:
Visible on <= sm:
Visible on sm...lg:
Visible on xs and md:
Col-md-6, offset 2:

Tooltips

  • The combobox is a select tag bearing the CSS-class form-control.
  • If the attribute required is true, the pseudo CSS class bf-required is added. Thus you can define your custom style for required fields.
  • If there's a FacesMessage, the input field is bears one of the pseudo CSS classes bf-info, bf-warning, bf-error or bf-fatal. If there are no messages, the input field bears the pseudo CSS class bf-no-message.
  • If there's a label, it bears the CSS class required, if it's a mandatory field. This class adds an asterisk to the label text. You can override the CSS class to remove the asterisk or to replace it by something else.
  • If there's a label, it bears the CSS classes bf-info, bf-warning, bf-error or bf-fatal, depending on which severity the error message the input field has. The latter two classes color the label red.
    If there's no message, the input field bears the pseudo CSS class bf-no-message.
