I have problem with the html code inserted in the body of the template from the GUI interface.

When the Save key is pressed, odoo alters the html code, it adds other lines of code.

If I do the same thing directly in the .xml file, odoo does not alter and the template is correct.

The user who must modify the content of the template, is not authorized to manage the .xml files, must be able to act as an interface.

It's possible?

thank you
