Builder lets you create your very own stack elements! You can use this stack to group together text, images, HTML, PHP, CSS, Javascript, various code libraries and third-party stack elements to create reusable partials, templates or externals. Likewise if you've discovered a useful code plugin or snippet online that you want to integrate with your RapidWeaver website, Builder could be the perfect tool to achieve this. Some RapidWeaver users swear by Builder and claim its one of the most frequently used stacks they use in their websites! The immense flexibility and near endless possibilities prove why this may be the case.
