Genesis Dambuster breaks out of the page-width constraints put in place by your child theme.
You can selectively switch off various aspects of a page or post. Not many plugins offer the ability to control pages and posts in this way.
So even if you’re not interested in landing pages you might use the plugin to remove the menu on a certain page, or remove the secondary menu on a certain page, or maybe the footer, or whatever.
It’s designed to work either with or without Beaver Builder Standard Version. This is because the Standard Version of Beaver Builder requires access to the full-width of your site for some of its page templates to work properly.
You can of course remove these manually by working out what is required and adding the code yourself, but using Genesis Dambuster is easier and you get more functionality too.
If you prefer to build landing pages without Beaver Builder, then Genesis Dambuster pre-prepares pages to receive your HTML and CSS. This removes most of the tedious work when building a landing page manually. Please view the demos for a fuller explanation.
