Is there a quick guide somewhere to guide me in making a block which has only one field that looks up post in a custom post type? I have CP with Videos and I want to create a Gutenberg block that retrieves the embed code of the CP so I can let people easily add videos into a post, without the need of searching for that video on YT again.
There isn't an easy way with a few clicks to render the custom block. You can create the custom block with the builder and use the code to render the block content and field value. Please follow the documentation https://docs.metabox.io/extensions/mb-blocks/#rendering-the-block
If you're not able to complete the task, we offer a customization service for an extra fee. Please contact us here for more details https://metabox.io/contact/
