i can hide the duplicate button/action in a form using this code:

                <xpath expr="//form" position="attributes">
                    <attribute name="duplicate">0</attribute>
                    <attribute name="delete">0</attribute>
                </xpath>

               

But how can i do same in tree-view?

i tried this but without success:

                <xpath expr="//tree" position="attributes">
                    <attribute name="duplicate">0</attribute>
                    <attribute name="delete">0</attribute>
                    <attribute name="export">0</attribute>
                </xpath
