I’m working with a custom module in Odoo 17 and I have a tree view (list view) for my model, for example hms.order.

Now I want to display a mini dashboard above the tree view, showing some KPIs like:

• Total number of records
• Total sales amount
• Average order value

I’d like this dashboard to appear above the tree view (not in a separate menu). Something similar to how Odoo shows small counters or summary stats above list views in native apps.

I’m not sure what is the recommended approach in Odoo 17 for this:

• Should I extend the tree view with a custom template (arch and xpath)?
• Or should I use a kanban dashboard combined with tree?
• Or do I need a custom client action / controller?

What’s the cleanest and future-proof way to implement this in Odoo 17?
