How to make MultiCheckBox Label bold or strong? - zend-framework2

Question

I have the following multicheckbox:
$this->add(array(
'type' => 'DoctrineModule\Form\Element\ObjectMultiCheckbox',
'name' => 'directPractice',
'options' => array(
'label' => 'A. Check all direct practice field education assignments',
**EDIT 1:**
'label_attributes' => array(
'class' => 'label-multicheckbox-group'
),
'object_manager' => $this->getObjectManager(),
'target_class' => 'OnlineFieldEvaluation\Entity\FieldEducationAssignments', //'YOUR ENTITY NAMESPACE'
'property' => 'directPractice', //'your db collumn name'
'value_options' => array(
'1' => 'Adults',
'2' => 'Individuals',
'3' => 'Information and Referral',
'4' => 'Families',
),
),
'attributes' => array(
'value' => '1', //set checked to '1'
'multiple' => true,
)
));
How to make the following part bold?
Using label_attributes makes all labels bold, and I want just the main label for the multibox be bold.
'label' => 'A. Check all direct practice field education assignments',
EDIT 1: add label_attributes to "options"
When I add label_attributes as #itrascastro suggested, all labels become bold and I want only the top one to become bold: multicheckbox

Answer 1

Try to add this to your options:
'options' => array(
'label_attributes' => array(
'class' => 'myCssBoldClass'
),
// more options
),

Answer 2

Each value option accepts an array of options.
For example
'value_options' => [
[
'label' => 'Adults',
'label_attributes' => [
'class' => 'my-bold-class',
],
'attributes' => [],
'value' => 1,
'selected' => false,
'disabled' => false,
],
'2' => 'Individuals',
'3' => 'Information and Referral',
'4' => 'Families',
],
I've added in some other values you can define; they are obviously optional.

Answer 3

Since there is no build in option to do this just for the top label, I used jQuery to accomplish this:
$("label[for]").each(function(){
$(this).addClass("label-bold");
});
