Get parent first:


<?php
$parentId = 25;
include('loop.php');

?>


Inside loop.php


<?php

global $post;
$args = array(
'type' => 'post',
'child_of' => 0,
'parent' => $parentId,
'orderby' => 'name',
'order' => 'ASC',
'hide_empty' => 1,
'hierarchical' => 1,
'exclude' => '',
'include' => '',
'number' => '',
'taxonomy' => 'category',
'pad_counts' => false
);

$categories = get_categories( $args );

?>

<!-- / Then get the Sub cats -->


<?php
// initialize the ctr
$ctr=1;

// get the last number
$lastItem = count($categories);

// loopiing..
foreach ($categories as $key => $value) {

if ($ctr==1)
{
echo '<li class="active">
<a href="#'.$value->slug.'" rel="bookmark"data-toggle="tab">'.$value->name.'</a>
</li> <span style="font-size: 30px;"> &bull; </span>';
}
else
{
echo '<li><a href="#'.$value->slug.'" rel="bookmark"data-toggle="tab">'.$value->name.'</a></li>';
if ($lastItem!=$ctr)
{
echo '<span style="font-size: 30px;"> &bull; </span>';
}
}

$ctr++;

}

?>


<div class="tab-content">

<?php

$contentCtr=1;
$classActive= "active";

foreach ($categories as $key => $value)
{
if($contentCtr!=1)
{
$classActive= "";
}

?>
<div class="tab-pane <?= $classActive?>" id="<?=$value->slug?>">
<div class="display-category-images">
<ul>
<?php
$args = array( 'category_name' => $value->slug, 'posts_per_page' => '20' );

$posts = get_posts( $args );

foreach( $posts as $post ): setup_postdata($post);

$image = wp_get_attachment_image_src( get_post_thumbnail_id( $post->ID ), 'single-post-thumbnail' );
$url = $image[0];

$idAction = str_replace('-', '', $value->slug)
?>

<li>
<a rel="candy" data-toggle="modal" data-target="#<?=$idAction.$post->ID?>" class="product">

<?php endforeach; ?>

</ul>

Hello,

Your code is something like this :

<?php

//get current category
$current_tax_id = intval(get_queried_object_id());

//get current category children
$get_term_childrens = get_term_children($current_tax_id, 'your_taxonomy'); //change me

//check if current category has children
if($get_term_childrens)
{
//loop
foreach($get_term_childrens as $term_children)
{
//you can use this variable to get category cetails
$term_children_id = intval($term_children->term_id);

/** -- children loop -- **/

//get children category children
$get_term_grand_childrens = get_term_children($term_children_id, 'your_taxonomy'); //change me

//check if child category has children
if($get_term_grand_childrens)
{
//grand children loop
foreach($get_term_grand_childrens as $term_grand_children)
{
//you can use this variable to get category cetails
$term_grand_children_id = intval($term_grand_children->term_id);

/** -- grand children loop -- **/
}
}
}
}

?>

hope this help :-)
