Content Attributes can be found in the Configuration menu within the Content area of the back office of Lead Commerce. Content Attributes are a powerful way to allow end users interact with content without having to have any knowledge of HTML markup.
Attributes are pulled into a specific .flex file by using Slugs. Slugs are a unique naming convention that get created automatically when you create a new Attribute. Slugs can then be referenced using the FLEX language to pull in what ever value is provided by the end user.
For Example:
<!-- Output the attribute value --> {attr_my_custom_attribute_slug}
