Block templates are section type templates available for Premium subscription owners in the Visual Composer Hub. Block templates allow you to build your WordPress site by adding section-size templates.
To access Block Templates, navigate to the Visual Composer Hub and open Blocks section.
As you download the block templates, they will be automatically added to your Template list. To add block templates, open the Template window, and select the downloaded template.
In addition, block template can be manipulated just like regular page templates, meaning you can adjust them to your liking and purpose.
