This plugin creates a basic accordion from custom posts. 
Fully compatible with WPML, just translate your posts and use shortcodes as explained below. 
The plugin currently does not support Woocommerce.
<h3>How to use</h3>
<ol>
<li>To use this plugin you need custom post registered. 
You may check <a href="https://codex.wordpress.org/Post_Types" title="Post Types" rel="nofollow ugc">Post Types</a> to see how to do it.</li>
</ol>
Example from WP Codex – for testing, copy and paste code below to theme functions.php
<pre><code> add_action( 'init', 'create_post_type' );
 function create_post_type() {
 register_post_type( 'Accordion',
 array(
 'labels' => array(
 'name' => __( 'Accordions' ),
 'singular_name' => __( 'Accordion' )
 ),
 'public' => true,
 'has_archive' => true,
 )
 );
 }
</code></pre>
<ol>
<li>Add shortcode to page or post where you want to use accordion</li>
</ol>
If you used code above to create custom posts type you would use following shortcode:
<pre><code>[gw_accordion post_type="Accordion"]
</code></pre>
Optionally, you may add CSS class
<pre><code>[gw_accordion post_type="Accordion" class="my_css_class"]
</code></pre>
You can also add code to your theme
<pre><code><?php echo do_shortcode('[gw_accordion post_type="Accordion"');?>
</code></pre>
or with the CSS class
<pre><code><?php echo do_shortcode('[gw_accordion post_type="Accordion" class="my_css_class"]');?>
</code></pre>
You also may set ordering, default is by ID and Ascending (ASC)
[gw_accordion post_type=”Accordion” class=”my_css_class” order_by=”title” order=”asc”]
<h3>Demo</h3>

</ol>
<h3>Known Issues</h3>
If your theme uses smooth scroll script like this one
<pre><code> jQuery(function() {
 jQuery('a[href*="#"]:not([href="#"]').click(function() {
 if (location.pathname.replace(/^\//,'') == this.pathname.replace(/^\//,'') && location.hostname == this.hostname) {
 var target = jQuery(this.hash);
 target = target.length ? target : jQuery('[name=' + this.hash.slice(1) +']');
 if (target.length) {
 jQuery('html,body').animate({
 scrollTop: target.offset().top
 }, 2000);
 return false;
 }
 }

 });

 });
</code></pre>
You may need to change this line
<pre><code> jQuery('a[href*="#"]:not([href="#"]')
</code></pre>
To look like this
<pre><code> jQuery('a[href*="#"]:not([href="#"], a:not([data-toggle])')
</code></pre>
to avoid conflict
