    As per, here.

    You just need to do this simple thing (From the example there only):

    HTML:

    <div class="row">
        <div class="col s12">
          <div class="row">
            <div class="input-field col s12">
              <i class="material-icons prefix">textsms</i>
              <input type="text" id="autocomplete-input" class="autocomplete">
              <label for="autocomplete-input">Autocomplete</label>
            </div>
          </div>
        </div>
    

    JS:

    $('input.autocomplete').autocomplete({
        data: {
          "Apple": null,
          "Microsoft": null,
          "Google": null
       }
    });

    You can use the above .js file and you can over ride

    Onselect
     showListOnFocus: false,
                minLength:2
    

    according to your requirement and it will work.

    Materialize is an awesome library, I was able to get it to work.

                var valueStr = self.value.map(function (selectedItem) {
                    return selectedItem.id;
                }).join(',');

        $.fn.materialize_autocomplete = function (options) {
            var el = this;
            var $el = $(el).eq(0);
            var instance = $el.data('autocomplete');
    
            if (instance && arguments.length) {
                return instance;
            }
    
            var autocomplete = new Autocomplete(el, options);
            $el.data('autocomplete', autocomplete);
            $el.dropdown();
            return autocomplete;
        };

    According to the commit done by SuperDJ (https://goo.gl/0Mbrtg), I didn't manage to get it works...

    Here is the code :

      <div class="row">
                    <div class="col s12">
                        <div class="row">
                            <div class="input-field col s12">
                                <input type="text" id="autocomplete" class="autocomplete highlight-matching" data-array='[{"value": "example","path": "","class": ""},{"value": "example 2","path": "","class": ""},{"value": "test","path": "","class": ""}]'>
                                <label for="autocomplete">Autocomplete</label>
                            </div>
                        </div>
                    </div>
                </div>
    

    Here is a codepen test :

    Visit the link for demo https://ampersandacademy.com/demo/autocomplete/

    you can easily achieve the autocomplete functionality using the Devberidge plugin.

    Get Devbridge plugin using https://github.com/devbridge/jQuery-Autocomplete

     <script type="text/javascript">
    
    $(document).ready(function() {
    
    
              $("#country").devbridgeAutocomplete({
                //lookup: countries,
                serviceUrl:"getCountry.php", //tell the script where to send requests
                  type:'POST',
    
    
                  //callback just to show it's working
                  onSelect: function (suggestion) {
                     // $('#selection').html('You selected: ' + suggestion.value + ', ' + suggestion.data);
                    },
                showNoSuggestionNotice: true,
                noSuggestionNotice: 'Sorry, no matching results',
    
    
              });
    
    });
    

    Here the getCountry.php file returns the JSON data. For more info visit https://ampersandacademy.com/tutorials/materialize-css/materialize-css-framework-ajax-autocomplete-example-using-php
