Thanks for a great plugin, we are using it in a customer project right now.
Advanced custom fields is a pretty well know plugin/framework and in acf5 there is support for using fields in widgets.
This is kind of cool since it makes it quite easy to create custom widgets very easy, which then could be used together your page builder to build even more customized websites.
However when I try this it seems like acf5 fields are not showing up when adding this widget with the page builder.
You can find acf5 through https://github.com/AdvancedCustomFields/acf5-beta
To show you I have put together this example.
I have created a field group with 2 fields that I have decided should show on the widget Meta. https://drive.google.com/file/d/0B18DXlchF8TxRTVJTTJXVnYtdFk/edit?usp=sharing
And it shows correct when I edit this widget in the regular WordPress widget administration. https://drive.google.com/file/d/0B18DXlchF8TxVUZzQXlYTzhBYk0/edit?usp=sharing
But when I add this widget in the page builder I don’t get the fields. https://drive.google.com/file/d/0B18DXlchF8TxTllCN0ZEQWljLWc/edit?usp=sharing
Really appreciate your help/thoughts on this, thanks.
