I've tried to insert a paypal form + button on a component's type description and once I save a part of the code is gone.
<form action="https://www.paypal.com/cgi-bin/webscr" method="post" target="_top">
<form method="post" target="_top">
Paypal form + button is working properly on Articles, but it's not working on Components. I would create a href link instead, but I need form fields info, and it seems I can only get the info with an input button.
I've also tried to insert an iframe and once I save it gets erased completely. It's working on Articles, tho.
