Hey there! To get your Employee tree view to only display staff from the HR, Audit, and Production departments, there are a couple of simple, effective ways to set this up in your XML configuration. Let me walk you through them:

Option 1: Add a Filter Directly to the Tree View #

You can embed a domain attribute right in the <tree> tag of your view. This applies the filter every time the view is loaded.

Here's a complete example of the view definition:

<record id="view_employee_filtered_tree" model="ir.ui.view">
    <field name="name">employee.filtered.tree</field>
    <field name="model">employee</field>
    <field name="arch" type="xml">
        <!-- The domain here restricts records to the specified departments -->
        <tree string="Filtered Employees" domain="[('e_dept', 'in', ['HR', 'Audit', 'Production'])]">
            <field name="e_name"/>
            <field name="e_num"/>
            <field name="e_addr"/>
            <field name="e_dept"/>
        </tree>
    </field>
</record>

What the Domain Does: #

The domain expression [('e_dept', 'in', ['HR', 'Audit', 'Production'])] tells the system to only fetch records where the e_dept field matches one of the values in the list.

Option 2: Set the Filter in the Action (Menu Entry) #

If you want the filter to apply whenever users access the employee list via a specific menu item, you can define the domain in the ir.actions.act_window record instead. This way, the filter is tied to the action, not just the view.

Example action configuration:

<record id="action_employee_filtered_list" model="ir.actions.act_window">
    <field name="name">Filtered Employees</field>
    <field name="res_model">employee</field>
    <field name="view_mode">tree</field>
    <!-- Apply the domain here -->
    <field name="domain">[('e_dept', 'in', ['HR', 'Audit', 'Production'])]</field>
    <!-- Link to your tree view -->
    <field name="view_id" ref="view_employee_filtered_tree"/>
</record>

<!-- Optional: Add the action to a menu -->
<menuitem name="Filtered Employees" id="menu_employee_filtered" action="action_employee_filtered_list"/>

Important Note for Related Department Fields #

If your e_dept is a relational field (e.g., linked to a hr.department model instead of a plain string), you'll need to adjust the domain to target the name field of the related model:

domain="[('e_dept.name', 'in', ['HR', 'Audit', 'Production'])]"

Hope this gets you sorted! If you run into any hiccups with field types or view inheritance, feel free to follow up.
