Hi,

In Odoo, the 'default_group_by' attribute is used to set the default grouping of records in a Kanban view. It allows you to define how records should be grouped when the Kanban view is initially loaded. This can be particularly useful for organizing and visualizing data based on a specific field or criterion.  

<kanban default_group_by="state">

group_create="false" for preventing the creation of a new stage, default value is True

default_group_by ->used for grouping the kanban cards.group_delete-> attribute is used for deleting a kanban groupgroup_edit-> used for editing purposeson_create="quick_create" ->This option is used for creating records quickly from the kanban view itself.quick_create_view-> Enter the view id
