[WooCommerce] [Woocommerce] Change template to add search form after header

Hi,

i’d like to add a search form and some html after the header of my woocommerce shop and product page. Did search the internet and find some articles saying that i have to edit the template files. Did try and add code in /wp-content/plugins/woocommerce/templates/archive-product.php

Problem: when i add before

"do_action( 'woocommerce_before_main_content' );"

the code is above the header (Screen1 / Screen2).

If i add after its over the product title but not full width (Screen3 / Screen4).

For better understanding i did add image of what i want achive (Screen5).

Do you have a idea?

Thanks in advance,

Andi
