I've read many add tabs post here, but can't seem to get any to work the way I need to work.
Attribute is 'sizechart' and is text field added to the default attribute set (but could be dropdown or multiselect)
In admin product add text to "sizechart" attribute eg "levi-size" ("levi-size' is name of CMS/Block already created in the backend).
The product page would then display the new tab with the CMS/Block
Since the size charts for different manufacturers aren't the same, I can't make a static tab, but need one which will use the custom test field or even better, a dropdown where the storefront labels contain the CMS/Block widget code such as below
{{widget type="Magento\Cms\Block\Widget\Block" template="widget/static_block/default.phtml" block_id="3"}}
I had this working very well in 1.9, but since 2.2, I can't seem to find a way to make this work.
The code I've seen here for Magento 2 and 2.1 doesn't seem to work for 2.2 and I'm not sure what the solution is. I expect this to go to bounty in a few days ...
Ideally, creating a drop down where the admin label is "oneill" and the storefront field is
{{widget type="Magento\Cms\Block\Widget\Block" template="widget/static_block/default.phtml" block_id="3"}}
witch would correspond to the oneill warranty information would be much better.
And the same for size charts as well.
EDIT: For 2.3.2, the tabs were before the product details. To change that, I added SORT to the catalog_product_view.xml
This is what I added
<referenceBlock name="product.info.details">
<referenceBlock name="product.info.description">
<arguments>
<argument name="sort_order" xsi:type="string">10</argument>
</arguments>
</referenceBlock>
<referenceBlock name="product.attributes">
<arguments>
<argument name="sort_order" xsi:type="string">20</argument>
</arguments>
</referenceBlock>
</referenceBlock>
Then, below my added tab I added
<argument name="sort_order" xsi:type="string">50</argument>
So the whole file looks like
<?xml version="1.0"?>
<page xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:View/Layout/etc/page_configuration.xsd">

</referenceBlock>
<referenceBlock name="product.attributes">

<argument name="sort_order" xsi:type="string">20</argument>
</arguments>
</referenceBlock>
</referenceBlock>
<referenceBlock name="product.info.details">

<arguments>
<argument translate="true" name="title" xsi:type="string">Size Chart</argument>
<argument name="sort_order" xsi:type="string">50</argument>

</block>
</referenceBlock>
</body>
