I manage a real state website that has a lot of Custom Fields. This ends up in a very long and heavy back-end when editing a real state. The browser gets very laggy and the UX overall isn’t good.
I improved it a bit by using ACF: Accordion Tab Field plugin (https://br.wordpress.org/plugins/acf-accordion/), the height of the page shrinked from 29893px to 4483px, just by tabbing the contents, but it is still laggy on the backend, because even if it’s hidden, it still have to load a lot of stuff.
Is there some kind of “ajax tab” or something that loads the fields on-demand? Or, how do I improve the back-end performance for such a lengthy page?
