this is my code and i do not want to non editable form edit="false" 
so what i do?

To hide the "Save" and "Discard" buttons on a specific custom form in Odoo 18, you can achieve this by customizing the form view using XML and adding a specific class or condition. Here's how you can do it: 1. **Identify the Form View**: Locate the form view that you want to customize. This is typically done in the form view XML file of your custom module. 2. **Override the Form View**: In your custom module, you can override the existing form view to add attributes or classes that will hide the buttons. You will need to use XPath to identify the buttons within the form view. 3. **Add Custom Attributes**: Use the `attrs` attribute to conditionally hide these buttons. You can apply conditions based on record data or simply hide them using CSS. Here's a basic example of how you might modify the form view in the XML: ```xml Custom Form your.model oe_hidden ``` 4. **Custom CSS (optional)**: If adding attributes is not sufficient, you may need to add custom CSS to hide these buttons: ```css .oe_hidden .o_form_buttons_edit { display: none !important; } ``` 5. **Restart Odoo and Update the Module**: After making these changes, restart the Odoo server and update your module to apply the changes. This approach specifically targets the form view you want to customize and hides the buttons without affecting other forms globally. Adjust the XPath expression and conditions as needed, based on your specific form structure and requirements.

Hi
In Odoo 18, the Save and Discard (Cancel) buttons in the form view header are added by default when the view is in edit mode.

If you want to hide them only for a particular form (or module) and not globally, you can do it by overriding the form view with create="false" and edit="false".

or 

try this,

<form edit="0">

Hope it helps
