Before publishing an answer, determine which interfaces and customers you want to be able to view the answer. You can control visibility with answer access levels, languages, products, categories, and conditional sections.
A conditional section is a section of text in a document that appears only to those contacts meeting certain criteria. Conditional sections can also be placed in answers and tagged with specific answer access levels. In message templates, conditional sections can be used to filter content by contact, profile, runtime variable, or record type.
