                <p>Set to show or hide the remove button. It is valid when <span class="highlight_red">[setting.edit.enable = true]</span>
                </p>
                <p>When you click the remove button:</p>
                <p>1. zTree will trigger the <span class="highlight_red">setting.callback.beforeRemove</span> callback,
                    and you can decide whether to allow delete.</p>
                <p>2. If you don't set the 'beforeRemove' or the 'beforeRemove' callback return true, so zTree will
                    trigger the <span class="highlight_red">setting.callback.onRemove</span> callback after remove the
                    node.</p>
