Hi amorino
This requires some customization, I will guide you some steps to achieve that:
1.Create new custom field: go to Backend > Content > Fields > create a new field type of Radio and add text as you desired: https://prnt.sc/phd2l8
- Load this field in the layout you wish.
In this template, there are some modules show the properties so you will need to edit relevant PHP layout file to load this new custom field, I will take Articles Category module as sample (the module called 'Best Offers This Week' on our demo site)
Go to file: /templates/ja_property/html/mod_articles_category/owl.php
Add this snippet of code to the place that you want to show up the 'available' label:
<?php if(!empty($customs['available-or-not'])) :?>
<span class="tag-label label-<?php echo $customs['available-or-not']->value ;?>"><?php echo Jtext::_('TPL_AVAI').' '.$customs['available-or-not']->value ;?></span>
<?php endif ;?>
like this: https://prnt.sc/phd53v
- Now you will have the available label on frontend, you will need to customize css to style for the label as you desired.
Hope this helps.
