Hi sunnyjey,
The JA Onepage template has a special layout named “onepage” layout containing only one position “onepage” that we created a new module style display the anchor ID at the title that menu items can link to.
function modChrome_onepage($module, &$params, &$attribs)
{
$key = strtoupper(str_replace (' ', '_', stripslashes($module->title)));
$subtitlekey = 'TPL_SUBTITLE_'.$key;
$subtitle = JText::_($subtitlekey);
$menuid = strtolower(str_replace (' ', '_', stripslashes($module->title)));
?>
<section class="section onepage<?php echo $params->get('moduleclass_sfx'); ?>" id="<?php echo $menuid ?>">
<div class="container">
<?php if ($module->showtitle != 0) : ?>
<div class="section-title" id="<?php echo $menuid ?>">
<h2><span><?php echo $module->title; ?></span></h2>
<span class="section-subtitle"><?php echo $subtitle ?></span>
</div>
<?php endif; ?>
<div class="row-fluid">
<?php echo $module->content; ?>
</div>
</div>
</section>
<?php
}
I did attach the modules.php containing the new onepage module style that you can try edit and put into templates/ja_template/html/ path.
