This is a prototype plugin that modifies Advanced Custom Field's Flexible Content admin interface.
This plugin injects some CSS + JS to modify the way sub flexible content fields are displayed within other flexible content fields. This allows you to use ACF like a page builder: https://www.youtube.com/watch?v=9c_Xa0gKWu4.
- Create a flexible content field and call it "Rows"
- Create descriptive layouts like "Single column", "Double Column" etc.
- Inside each of those layouts include another flexible content field.
- Use these sub flexible content fields to provide the "block" options for your page builder.
