Thank you Pawan, but i tryed your solution and it does not work 

Hi,

In the XML code you provided, there is a spacing issue in the attrs attribute value for the invisible attribute. There is an extra space before and after the autre_id field name, which causes the attribute to not work as expected.

To fix the issue, you can remove the extra spaces in the attribute value as follows:

<field name="autre_id" attrs="{'invisible': [('autre_id', '=',False)]}"/>

That might be the Issue you are facing.

If u still having the Issue these are the ways you hide a field using XML

1. To hide a field using XML view, you can add the "invisible" attribute to the field and set it to "1". This will hide the field in the view. 

For example:

<field name="autre_id" attrs="{'invisible': [('autre_id', '=',False)]}"/>

2. Another Way, To hide a field using groups, first, you need to define a group by creating a record for it in the "res.groups" model. For example:

<record id="my_module.my_group" model="res.groups"> <field name="name">My Group</field> </record>

Then, you can add the group to the field's access rights using the "groups" attribute. For example:

<field name="my_field" groups="my_module.my_group"/>
