Extended select field call threshold

  • i have a select field filled with many values filled using add_filter(‘acf/load_field/name=searchfield’, ‘my_acf_load_field’); I set the field to extended and activated the ajax mode on it.

    because of the number of options, it hangs all the time even directly when i click it for the first time(without any input in it).

    Can you tell me where to edit the acf-pro-input.js so it won`t start searching until at least 3 chars are filled in? Or is there another trick to make it suitable for big data collections?

  • Hi @niceguys

    If you want to start searching after 3 chars, you can try this code:

    add_action('acf/input/admin_footer', 'my_acf_admin_footer7');
    function my_acf_admin_footer7() {
        <script type="text/javascript">
        (function($) {
                acf.add_filter('select2_args', function( args, $select, settings ){
                    args.minimumInputLength = 3;
                    // return
                    return args;

    This page should give you more idea about it:

    I hope this helps 🙂

  • Thank you very much James!
