papa ma ka makua .dropdown-menu
. Ua data-bs-toggle="dropdown"
hilinaʻi ʻia ka ʻano no ka pani ʻana i nā menus dropdown ma kahi pae noi, no laila he manaʻo maikaʻi e hoʻohana mau ia.

quirk i ka ʻelele hanana hanana ʻo iOS , i ʻole e pale i kahi paʻi ma waho o ka hāʻule iho mai ka hoʻomaka ʻana i ke code e pani i ka hāʻule. Ke pani ʻia ka hāʻule iho
mouseover
, wehe ʻia kēia mau mea lima ʻole.
Ma o nā hiʻohiʻona ʻikepili
Hoʻohui data-bs-toggle="dropdown"
i kahi loulou a i ʻole pihi e hoʻololi i kahi hāʻule iho.
<div class="dropdown">
