Map<String, Icon> dataMap = Map.of(
        "ly-yxwz-ui", ImageUtils.JSX_DARK,
        "ly-yxxt-ui", ImageUtils.JSX_DARK,
        "ly-gyxt-ui", ImageUtils.JSX_DARK,
        "ly-xtgl-ui", ImageUtils.JSX_DARK,
        "ly-xtgl-svc", ImageUtils.SPRINGBOOT_DARK,

        "ly-yxwz-svc", ImageUtils.SPRINGBOOT_DARK,
        "ly-gyxt-svc", ImageUtils.SPRINGBOOT_DARK
);
completion = FastTextFieldWithAutoCompletion.create(project);
completion.setPreferredSize(290, 30);
completion.setItems(dataMap.keySet().stream().toList());
completion.setItem2IconMap(dataMap);

jPopupMenu.setPopupSize(300, 55);
jPopupMenu.setLayout(new BorderLayout());
jPopupMenu.add(completion, BorderLayout.CENTER);

（FastTextFieldWithAutoCompletion is a class I directly wrote, which inherits TextFieldWithAutoCompletion and simplifies some operations）
