Version 8.0 introduced smart buttons, shown as rectangles with a statistic indicator that can be followed through when clicked. The top-right area can have an invisible box where smart buttons can be placed.
This button box is usually added to the form just before the <div class="oe_title"> element (and avatar image), with the following:
<div name="button_box" class="oe_button_box"> <!-- Smart buttons will go here... --> </div>
The container for the buttons is just a div with the oe_button_box class.
In Odoo versions before 11.0 you might need to also add the oe_right class, to ensure that the button box stays aligned to the right-hand side of the form.
We will be discussing buttons in more detail in a later section, ...
