How to change the bootstrap caret pointing direction on click event
提问by chalo
I'm using 2.3.2 bootstrap
我正在使用 2.3.2 引导程序
As I can change the position of the caret icon when I click the menu button.
因为我可以在单击菜单按钮时更改插入符号图标的位置。
I need that when I click the icon caret pointing up and when you click on another item the caret back to the initial state.
我需要当我单击指向上的图标插入符号时，当您单击另一个项目时，插入符号回到初始状态。
How is this possible?
这怎么可能？
