1. Create a custom course block : https://wplms.io/support/knowledge-base/creating-custom-featured-block-style/
Note the name of the block, in above example it is : custom_block
2. Copy the file : taxonomy-course-cat.php from the parent WPLMS theme into the child theme
3. Edit the taxonomy-course-cat.php
Locate the line :
echo ‘<div class=”col-md-4 col-sm-6 clear3″>’.thumbnail_generator($post,’course’,’3′,’0′,true,true).'</div>’;
and change it to :
echo ‘<div class=”col-md-4 col-sm-6 clear3″>’.thumbnail_generator($post,’custom_block’,’3′,’0′,true,true).'</div>’;
To change the number of courses in one row from 3 to 4 , use this :
echo ‘<div class=”col-md-3 col-sm-6 clear4″>’.thumbnail_generator($post,’course’,’4′,’0′,true,true).'</div>’;
