Hello,
I’m experiencing severe performance issues in the WordPress admin panel when editing posts that use deeply nested ACF repeater fields.
Specifically, I have a structure like this:
Part (repeater)
Chapter (nested repeater inside Part)
Article (nested repeater inside Chapter)
In some cases, a single post may contain 100+ articles. When I open the post in the editor, the admin screen becomes extremely slow or even unresponsive for several seconds to minutes.
I understand that deeply nested repeaters may not be optimal, but given my use case, I can’t easily switch to custom post types or restructure the data model.
Is there any recommended way to handle large nested repeater structures more efficiently?
Any guidance or best practices would be appreciated.
Thank you!
