I’m using this code I found on the forum:
add_filter( 'generate_header_element_display', function( $display, $element_id ) { global $post; if ( 23059 === $element_id && ( is_page() && 8418 == $post->post_parent ) ) { $display = true; } return $display; }, 10, 2 );I’m actually using two. One to show a content template for subpages of page 8418, and one for the page layout (= no sidebar, no title).
Within the element I tried to set the general display rule to all pages, whole site, or the page title of the parent page (8418).
In all cased the blocks I added in the content template element show on ALL pages of the website, not just the subpages of that parent page.
Am I missing something?
PS I changed generate_hook_element_display into generate_header_element_display after a suggestion by Tom on another topic, but in my case that makes no difference.

I found this topic
https://generatepress.com/forums/topic/gp-hook-on-certain-child-pages/#post-1056464
but that doesn’t work either in my case. All pages loose their design, as if no content layout is present anymore on any page.

Thank you AI…
This is the corrected code, and with this it is okay to leave the display rule in the element to ‘Entire site’.
add_filter( ‘generate_element_display’, function( $display, $element_id ) {
global $post;// Replace 23059 with your Content Template Element ID
if ( 23059 === $element_id ) {
if ( is_page() && $post->post_parent == 8418 ) {
return true; // show element
} else {
return false; // hide element
}
}return $display;
}, 10, 2 );This sub pages thing added to the display rule options in an element would be nice 😉

My fault was not knowing about the differences of the filters.
AI:
You’re using the filter generate_header_element_display, but your element type is a Content Template, not a Header. Each element type has its own display filter in GeneratePress Premium:
Header Element → generate_header_element_display
Hook Element → generate_hook_element_display
Layout Element → generate_layout_element_display
Block Elements (like Content Templates) → generate_element_displaySo in your case, you need to switch to generate_element_display.

Glad you’ve got this sorted 🙂
