Hi giuse74,
In order to customize this module, you can copy ‘default.php‘ file in folder of this module modulesmod_jaquickcontacttmpl
To: templatesja_template_namehtmlmod_jaquickcontact folder
then custom the default.php file in template folder as you wish.
Under the <form> tag, you may need to add:
<li class="<?php echo $params->get('moduleclass_sfx','')?>wide">
<div class="<?php echo $params->get('moduleclass_sfx','')?> input-box">
<input type="checkbox" name="term_required" id="term_required" value="1" />
<label for="term_required">
<?php echo JText::_( 'TERM_REQUIRED' ); ?>
</label>
</div>
</li>
In bottom of this file, add this JS code:
if($('term_required').checked == false){
$('term_required').getParent('li').addClass('error');
ck = false;
}
else
{
$('term_required').getParent('li').removeClass('error');
}
It must be confirmed that this is custom work and you should hire a developer to get this done for you.
