项目中某些下拉列表选项很多，有的上百个，用户使找某个选项十分不方便，本人基于jquery做了一个可输入的下拉列表，可以选择直接某项，也可以输入前几个字符进行提示，再选择需要的选项-Project a lot of some of the drop-down list of options, and some hundreds of users is very inconvenient to find an option based on jquery, I do a drop-down list input directly to an item, you can choose, you can enter the first few characters of the prompt, and then select the desired option
