【问题描述】:
我想我一整天都在想这件事。应该没那么难……
我有一个带有主菜单的 div,它是带有子菜单的子菜单。我最初的问题是想在屏幕上以绝对定位显示子菜单水平而不是垂直,这样我就可以把它放在我想要的地方。现在我遇到了这个烂摊子,我认为过度考虑情况已经让我迷失了。
我只想在将鼠标悬停在父级上后将子菜单与父级分开,然后只要您在父级或子菜单上就保持它,并在您离开时将其淡出,将附加的子菜单放回父母。将鼠标悬停在具有子菜单的父级上时徽标会淡出,并在子菜单淡出时淡入。无论如何,它现在所做的就是在徽标中逐渐消失,并且在将鼠标悬停在子菜单上时确实有问题,而且有时悬停在它上面时根本不会停留。
如果有更好的方法来定位它,这样我就不必经历这个混乱,或者只是整体上更好的方法,请指出。
