Hi @shaon007 ,
We are sorry for your inconvenience. So you want a <h2> tag before the label.
Basically, it is coming from WooCommerce not from our plugin. You can customize a template by following below procedure-
Create a child theme first and then inside your child theme create a folder woocommerce inside your child theme folder.
Inside the woocommerce folder create folders like the following-
single-product > add-to-product
Then copy variable.php from wp-content > plugins > woocommerce > template > single-product > add-to-cart
And paste it in your child theme > woocommerce > single-product > add-to-product, edit variable.php like this.
After doing the above you will get <h2> on the frontend like this.
Thanks
