Kivy Python试图将同一屏幕分割成独特的部分

我有一个问题，我想有一列按钮下拉下来的左侧应用程序，每个按钮是一个不同的随机生成器。我希望下拉列表和按钮占据大约20-30%的屏幕空间，应用程序中/右侧的其余部分显示每个下拉列表包含的生成器的输出。目前我看到的是，一旦我添加了足够多的下拉列表，我到达了输出的位置，下拉列表就会将文本推到陌生的地方，反之亦然。我尝试将标签或下拉列表放入不同形式的布局中，并使用pos、pos_提示或Size_提示选项移动项目，但没有任何运气

我有一个尝试使用screenmanager的想法，但理想情况下，我希望这一切都在一个屏幕上，而不是跳转到多个屏幕。有没有办法将这两个部分分开，这样它们就不会相互影响

以下是我的python代码：
