Hello @tflbearing,
Apologies for the delay in getting back to you.
The post category archive pages will use the theme layout, the same as the blog archive page.
You’ve said, “Maybe I didn’t express it clearly, what I mean is how can I use the page builder to edit the page. Is to use Kadence Blocks for custom editing.”
If you do have a page builder plugin like Elementor, you can create your own category template. However, you cannot use Kadence Blocks in Elementor.
If you do not use a page builder plugin, the default WordPress options for post categories are only for title and description.
Hope this helps further.
Regards,
Karla
