Thanks for the Response Elise,
I want to remove the category list banner from the All Products page(shop-2/ page).
And what looked for the code and, I spotted that in the inc/template-tags.php file and I wanted to override that through the child theme.
So, I placed that file under my child theme(wp-content\themes\woodmart-child\inc\template-tags.php), and did changes. But it doesn’t reflect on my website. If I do the change to the original, it reflects. Child theme selected and my other changes (I did some changes for the dokan reg. form) reflects, but this doesn’t.
