Content Blocks (Custom Post Widget) – Johan van der Wijk
This is a very useful mechanism to make content easy to find and then edit.
1. Create a new content block and give it a good short name and also a longer description.
2. Place the content here, text, images most types can be accommodated.
3. Then save and copy the short code provided. This needs to be place in the desired actual location for the content. If it needs to live on a template it will need to be wrapped in php More info.
