How to implement a navigation panel in tree view in Odoo?

Question

I want to implement a side navigation panel like the one in the Chart of Accounts view in Odoo

I can't find any documentation for this feature, how to implement it?

Answer 1

This is the searchpanel . By default, it is enabled on the the list view.

To implement it to any tree view, you have just to define the searchpanel in the search view.

For chart of accounts, they used the following:

<searchpanel class="account_root">
    <field name="root_id" icon="fa-filter" limit="0"/>
</searchpanel>
