devbridge自动完成类别

Question

我有以下代码

$autocompleteSearchInput.each(function() {

                    const $that = $(this);
                    $that.autocomplete({
                        minChars: 4,
                        serviceUrl: '/internals/site-search',
                        dataType: 'json',
                        paramName: 'search_string',
                        groupBy: 'category',
                        transformResult: function(response) {
                            return {
                                suggestions: $.map(response.results, function(value) {
                                    let node = JSON.parse(value);
                                    let title = (typeof node.field_title !== 'undefined') ? node.field_title[0].value : node.title[0].value;
                                    let data = (typeof node.uri !== 'undefined') ? node.uri : node.path[0].alias;
                                    let type = (node.type[0].target_id === 'property') ? 'Properties' : 'Other Results';

                                    return {
                                        value: title,
                                        data: {
                                            data:data,
                                            category: type
                                        }
                                    };
                                })
                            };
                        },
                        onSearchComplete: function(query, suggestions) {
                            if(suggestions.length > 0) {
                                // add autocomplete-active class to the input when dropdown is show (remove radius on bottom corners)
                                $that.addClass('autocomplete-active');
                            }
                        },
                        onHint: function(hint) {
                            return false;
                        },
                        onHide: function() {
                            $that.removeClass('autocomplete-active');
                        },
                        onSelect: function (suggestion) {
                            // If selecting an individual item, direct the user to the node directly
                            window.location.href = suggestion.data;
                        }
                     });
                });

使用以下代码类别时，始终显示类别标题。我如何才能做到，如果数据集仅包含“其他结果”或“属性”，那么我们不显示标题？
