EDIT：我简化了应用程序，并使其所有代码都是可复制的。编辑2：我刚刚发现，当我使用navBarPage时，我必须单击"附加参数"->"颜色"。然后按预期着色。
我正在开发一款闪亮的应用程序，它可以过滤我的基因，然后绘制剩余基因的热图。最近，我发现了shinyHeatmaply包。我已经下载了它们的全局、UI和服务器，当我在自己的电脑上尝试时，它们会按预期工作。不幸的是，当我尝试使用navbarPage将我的过滤器应用程序和他们的热图组合在一起时，最后一个没有正确呈现。
我创建了一个极简主义的例子，将shinyheatmap添加到https://shiny.rstudio.com/gallery/shiny-theme-selector.html应用程序，但我还是得到了同样的灰色渲染。
在更简单的应用程序中出现相同错误
用户界面：Navbar 1属于shinytheme应用程序，而Navbar 2的内容属于shinyheatmaply

提前感谢解决这个问题的英雄。最好的奖励，丹尼尔。
问题是条件面板(使用js)和导航栏页面之间的冲突，由于任何原因，默认参数都没有读取，因此应该启用的自动着色没有启用。我刚刚删除了这个条件面板，并始终设置它的选项。
