Question: If I display it by “Tab information”, it will display as a first tab. How do I move it to middle or last tab?? I’d like to have the 1st tab for “Product Detail” tab. 


Answer:

Please edit file /chroot/home/cuteprin/cuteprinting.com/html/vendor/magento/module-catalog/view/frontend/layout/catalog_product_view.xml 
Line 22:

<referenceBlock name="product.info.details">

        <block class="Bss\SizeChart\Block\SizeChartTab" name="bss_sizechart_tab" after="product.attributes" template="Bss_SizeChart::SizeChartTab.phtml" ifconfig="bss_sizechart/bss_sizechart_setting/enable_bss_sizechart" group="detailed_info">

               <arguments>

                    <argument name="sort_order" xsi:type="string">[sort_order number]</argument>
                </arguments>
        </block>
</referenceBlock>


Edit the sort_order number with the number compare with other tabs.
