MVC and AJAX options and ajax searching

How Do I...
#1

I am using Select2 for a list of items which i populate from the MVC Model on the page load (which are options that i have dealt with before) but when I add my AJAX call and MinimumInputLength = 7 it hides the options from the model and I can only search for them or new items using my ajax call, is there a way i can show the prepopulated ones from the model and also search using my ajax call but if i do not input anything in the searchbox it shows me the prepopulated ones?

 @Html.DropDownListFor(model => model.LinkedItems[i].ItemId, new SelectList(Model.GetItems, "Value", "Text", Model.LinkedItems[i].ItemId), "Item Name", new { @class = "form-select item-select-2" })

$('.item-select-2').select2({
    language: {
        errorLoading: function () {
            return "No itemfound.";
        }
    },
    width: 'resolve',
    theme: 'bootstrap-5',
    minimumInputLength: 7,
    
    ajax: {
        url: '/get-items',
        async: true,
        delay: 250,
        dataType: 'json',
        data: function (params) {
            return {
                q: params.term
            };
        },
        processResults: function (data) {
            return {
                results: $.map(data.Results, function (item) {
                    return {
                        id: item.Id,
                        text: item.Text
                    };
                })
            };
        }
    }
});
