The particular option should be enabled to apply categories. See the picture below.
Categories should be typed as a list separated by comma ‘,’ by names, slugs, or ID’s (case insensitive). Because slugs and ID’s are unique in WordPress, so it can be used without pointing parents. However, when names are used they should be typed with all parents that are separated by slash ‘\’.
Note: Only already existed categories can be specified.
Categories can be set in two sources:
- The ‘Categories’ property of MS Word document.
- The extended attribute in the document named ‘categories’, ‘category’, ‘Categories’ or ‘Category’.
And, it can be chosen by click on the link which source to use (see picture above). There are three modes:
- separate attribute
Extract only from the extended attribute.
- separate attribute and ‘categories’
Extract from document’s ‘Categories’ property and extended attribute. Data will be merged.
Extract only from the document’s ‘Categories’ property.
