Boilerplate gives you the ability to create quickly, edit, and remove repetitive pages or posts across your network of child sites.
How Boilerplate Extension Works?
After installing the extension, you can create custom placeholders (Tokens) that you will need in your commonly used pages and posts. For each of your child sites, add values for the tokens. When you finish the setup, you can create one page with these placeholders and post to all wanted sites. On each child site, the placeholders will get replaced with the custom values for the site.
All your Boilerplate Pages and Posts will get saved and fully editable. With just a few clicks, you will be able to tweak a page in all your sites at once.
