Show Header only when see.
I have the question of how I can hide the header in creation mode and edit mode; want it to show only when they are referring to a form.
Try using the CSS class "oe_view_only" and could not.
<form string="People" version="7.0">
<header class="oe_view_only">
<button string="Wait" name="button_assists" states="assigned" type="object"/>
....
</header>
...
</from>
