BUG

[YSZeng]

1、BUG:点击选项容器的滚动条，无法阻止 onBlur 的隐藏事件。导致只能使用鼠标滑轮滚动。
2、没有提供触发函数，只能通过文本框的焦点事件触发，当我希望从其他按钮触发全部显示的时候，不方便。（列：我在文本框后面提供下拉箭头）

1. BUG: Click the scroll bar of the option container, which cannot prevent onBlur from hiding events.This results in scrolling only with the mouse pulley.
2. No trigger function is provided, which can only be triggered by the focus event of the text box, which is inconvenient when I want to trigger all display from other buttons.(example: I provide the drop-down arrow after the text box)
