在 jQuery 的现有下拉列表中添加自动完成搜索

Question

我有填充符号列表的下拉菜单。我需要添加自动完成搜索，用户可以通过下拉列表进行搜索。当用户开始输入时，需要显示带有指定文本的 div。这是我用于下拉菜单的 JS。 知道如何使用现有代码包含自动完成搜索。

JS

$(document).ready(function () {
    $("#watchList").click(function () {
        $("#watchList_Popup").removeClass('animate');
        $("#watchList_Popup").show();
        $("#add_Instrument_Popup").hide();
    });
    $("#watchList_Popup_Close").click(function () {
        $("#watchList_Popup").addClass('animate');
        setTimeout(() => {
            $("#watchList_Popup").hide();
        }, 150);
    });

    $("#add_Instrument").click(function () {
        $("#add_Instrument_Popup").removeClass('animate');
        $("#add_Instrument_Popup").show();
        $("#watchList_Popup").hide();
    });
    $("#add_Instrument_close").click(function () {
        $("#add_Instrument_Popup").addClass('animate');
        setTimeout(() => {
            $("#add_Instrument_Popup").hide();
        }, 150);
    });

})

HTML
