Hi Rita,
You will need to edit 2 files:
root/templates/ja_medicare/etc/extrafields/doctors.xml
root/templates/ja_medicare/html/mod_jacontentslider/default.php
The 'doctors.xml' file will define extra fields that you see in the article setting, for example:
<field name="facebook_link"
type="text"
default=""
label="TPL_EX_FACEBOOK_LINK"
description="TPL_EX_FACEBOOK_LINK_DESC" />
and in the 'default.php' file of JA Content Slider module, it will render the value you set in article for each social link:
<?php
//Check extrafields
if($extrafields['facebook_link']): ?>
<a href="<?php echo $extrafields['facebook_link'];?>" class="ja-slidesocial-facebook"><i class="fa fa-facebook"></i></a>
<?php
endif;
?>
as you can see in the code, it uses FontAwesome icons: fa fa-facebook to show facebook icon there.
