I have following Odoo form view:

<group class="o_group_col_4">
 <field name="start_time"/>
 <field name="finish_time"/>
 <field name="readonly_field1" attrs="{'readonly':True}"/>
</group>
<group class="o_group_col_4">
 <field name="readonly_field2"  attrs="{'readonly':True}"/>
 <field name="date"/>
</group>

In the form view when I press TAB key from start_time, it goes to end_time but form end_time it does not go to date field on TAB.

Can anyone help how can we specify tabindex in odoo form view, so that the TAB navigation becomes start_time -> end_time -> date?
