Woocommerce: Refund amount – set to “readonly”

Hello @gb1231,

If I understand you correctly, you want to disable the following two fields and make them read-only.

This is a bit outside our scope of support here in the forums. That said, went ahead and wrote this simple snippet to make both fields read-only. You can insert it using the Simple Custom CSS and JS plugin.

document.getElementsByClassName("refund-items")[0].addEventListener("click", myFunction); 

function myFunction() {
  document.getElementsByClassName('refund_line_tax')[0].readOnly = true;
  document.getElementsByClassName('refund_line_total')[0].readOnly = true;
} 

Please make sure to make the snippet load in the footer and select “In Admin” as highlighted below.

The end result is this, you can only edit the quantity of the product to be refunded.

Hope this helps!
