The customer reported that one of the custom field groups and one of the custom fields are not appearing in the dynamic source settings for the "Single field" block.
Solution:
Checked the website using the provided admin access and noticed that the mentioned custom field group and the custom field were available now.
The customer wanted to know if there is a way to set the image from a Toolset term field, as a background in a Beaver Builder template for the taxonomy archive.
Solution:
Guided that this is possible and when you click the dynamic source option icon in the row's background settings, the dropdown includes the "Archive Term Meta" option.
Once, you select this option it asks for the field key and if you include the term field's key with the "wpcf-" prefix, it correctly gets the background image from the related term field.
