The method enableFilteringMode(true) is cool , when i type some chars ,it help me filer some matched option , and then i choose the most properful option which i really want .
But there’s the issuee , when i choose an option , and then i click the drop-down , i still can see the choosen option , i can’t see others . I still want to see the whole list .
How could i make that ? Thanks for all the advices from all you guys .
