We tried lots of solutions here/there/anywhere and they didn’t work for us, we have a series of complex flex content fields and lots of custom post-types, not all layouts need to be used in all post types. We come out with this, maybe help someone:
The basic idea is to hide the layout from the acf popup.
This hides 3 layouts from the ACF Popup when you click ADD ROW in POSTS.
function acf_flex_layouts_filter() {
$type = get_post_type();
if ($type=="post"):
?>
<style>
.acf-fc-popup a[data-layout='layout_name_1'] { display: none; };
.acf-fc-popup a[data-layout='layout_name_3'] { display: none; };
.acf-fc-popup a[data-layout='layout_name_8'] { display: none; };
<style>
<?
endif;
}
add_action('admin_head', 'acf_flex_layouts_filter');
You adapt it to your needs.
We created arrays with Layouts to hide for every post types:
$hide_laypout['post'] = array( 'lay1','lay2,'lay3'...);
$hide_laypout['page'] = array( 'lay8','lay9' ...);
$hide_laypout['movie'] = array( 'lay7','lay3' ...);
etc etc ...
And loop then inside <style> </style>.
Not sure if is the best solution but works for us.
