Instead of manually replicating content, the editor gives you the possibility to import content from another website through the Import Content functionality. This can be done both for Global Data but also for Columns, at the page level.
Using Import Content
This functionality makes it easy to import content from existing websites and add it to your own. In case of Global Data, you can choose which elements to use and to which field to apply them to. At the column level, you can choose which elements to use and the editor will automatically include them in the columns within the relevant modules. Learn everything about importing content here!
