With a WordPress Child theme, you can easily change core behavior and override certain files from plugins or the main theme. In this tiny tutorial, I show you how to change a WPBakery element with t child theme.
Copy the original template file
Head over to this folder and find the element you want to change: „/wp-content/plugins/js_composer/include/templates/shortcodes„
Create a folder in your child theme
To override the template file you need to create a folder in your child theme directory and put the modified version of the template file in there: „/wp-content/themes/child-theme/vc_templates“ or„/wp-content/themes/child-theme/vcex_templates“ (if using the total theme).
Bonus tip: Here you find all the according JS files
This is the folder where all JS files i.e. for the accordion element reside: „/wp-content/plugins/js_composer/assets/lib/vc_accordion„. unfortunately I guess you cannot override these with a child theme. But I am not sure.
Bonus tip 2: Total Theme user
If you are using the wonderful total theme you find the additional templates in this folder: „/wp-content/plugins/total-theme-core/inc/vcex/templates“ and copy them to:„/wp-content/themes/child-theme/vcex_templates“ (if using the total theme).
