Using groups to organize forms

The <group> tag allows you to organize form content. Placing <group> elements inside a <group> element creates a two-column layout inside the outer group. It is advisable for group elements to have a name attribute so that it's easier for other modules to extend them.

We will use this to better organize our content. Let's change the <sheet> content of our form to match this:

<sheet> 
  <group name="group_top"> 
    <group name="group_left"> 
      <field name="name" />
      <field name="author_ids" widget="many2many_tags" />
      <field name="publisher_id" />
      <field name="date_published" />
    </group> 
    <group name="group_right"> 
      <field name="isbn" /> 
      <field name="active" /> 
      <field name="image" widget="image" />
    </group> 
  </group> 
</sheet>
