Restoring the Seamless Style in ACF
If you use the excellent Advanced Custom Fields (ACF) WordPress plugin and the Gutenberg editor you may notice the seamless style has no effect.
Choosing either Standard (WP metabox) or Seamless (no metabox) has no visual effect on the ACF field group.
ACF removed the seamless styling from Gutenberg editor due to “due to styling conflicts / UX issues”
Solution
I developed a free WordPress plugin called ACF Seamless. This plugin will restore the seamless style to ACF Field Groups when using the Gutenberg editor.
Once you install and activate the plugin you’ll notice any ACF field groups with the seamless style will once again look…seamless!
