By using content blocks you can display content in a Page depending upon the Exhibitor Type / Stand Type combination.
IF Stand Type = Shell Scheme THEN display a special content block with information specifically about shell scheme construction. If the exhibitor does NOT have a Shell Scheme Stand Type then they wont see the content.
To add a content block simply click Add some content (using WYSIWYG editor) and then choose the stand type/exhibitor type top display that content to.
After creating your content block - the system will create a tag like this [CONTENT_content-block-name] which you can copy and then add to a Page.
