下拉菜单被身体切断

我非常坚持这个。我有一个下拉菜单，当它溢出div时被切断。

在大多数情况下，我遇到过这是因为某些父元素有溢出：隐藏或未设置z-index，但我已经尝试过两者都没有效果......

这是代码：

@import url(https://fonts.googleapis.com/css?family=Catamaran);
body,
html {
  margin: 0;
  padding: 0;
  background-color: #aaf44d;
  overflow: visible;
}

html {
  font-family: "Catamaran", serif;
}

body {
  font-family: inherit;
  background-image: linear-gradient(216deg, #c8ff40, #a7eba2, #16ac2a);
}

textarea,
select,
button {
  font-family: inherit;
}

#submit {
  padding: 4px 10px;
  background-color: #1b9c34;
  border: 0 none;
  cursor: pointer;
  color: white;
  -webkit-border-radius: 5px;
  border-radius: 5px;
  font-family: inherit;
  font-weight: bold;
}

#submit:hover {
  background-color: lightgray;
}

#submit:active {
  background-color: #1b9c34;
}

header {
  display: -ms-flexbox;
  display: -webkit-box;
  display: flex;
  background-color: #2f2f2f;
  border-bottom: 1px solid #37374a
}

h1 {
  color: white;
  height: 40px;
  line-height: 40px;
  vertical-align: middle;
  margin-left: 20px;
}

h2 {

  color: transparent;
  background-image: linear-gradient(216deg, #c8ff40, #a7eba2, #16ac2a);
  font-weight: 400;
  z-index: 3;
  text-align: center;
}
