O lenei hack e ta'utinoina mataga e mana'omia e galue fa'ata'amilo i se fa'alavelave i le tu'uina atu o mea e fai a iOS , lea e ono taofia ai se pa'i i so'o se mea i fafo atu o le pa'u i lalo mai le fa'aosoina o le code e tapuni ai le pa'ū. O le taimi lava e tapuni ai le pa'u i lalo, o nei isi fa'aoga gaogao mouseovere aveese.

E ala i fa'amaumauga uiga

Fa'aopoopo data-toggle="dropdown"i se so'oga po'o se fa'amau e fa'asolo i lalo.
