How to add new menu ……………………..

Hello @chutipao,

As you are utilizing our XStore Single Product Builder with the Elementor editor, you can navigate to Dashboard -> XStore Builders (located in the top bar panel) -> Single Product -> Go to Builder -> Edit with Elementor. There, you will find the Single Product Tabs widget, which you can edit by clicking on it. In the widget settings, you have the option to add a new tab and select the ‘Custom Tab’ type. Please refer to this link for guidance: https://gyazo.com/9abfaf438036f41f120a7c16d09db330. Should you require further assistance, kindly provide us with the appropriate temporary wp-admin access in the private content section.
