飛出垂直菜單中的重疊菜單項（Z-Index沒有幫助！）

Question

任何CSS專家都可以幫我找出Fly Out Vertical Menu項目重疊的原因，如屏幕截圖所示。 我嘗試使用更高的z-index用於ul，li，菜單包裝等，但無濟於事。

我正在使用Safari。

任何幫助將不勝感激，可以考慮自由職業。

感謝和問候

Answer 1

yes z-index幫助我們避免元素重疊...使用z-index最大值進行滑動，並使用列表項的z-index最小值。

Answer 2

我相信你走在正確的軌道上，只是以相反的方式做z-index。 在wowslider上放置一個更高的z-index，在列表上放一個更低的z-index。
