title: How do I use tagList() in a Shiny module?
body: <p>The official <a href="http://shiny.rstudio.com/articles/modules.html" rel="noreferrer">tutorial by RStudio</a> is a little unclear on how to actually use the tagList() function for creating a namespaced ID in Shiny modules. The <a href="https://www.rdocumentation.org/packages/shiny/versions/0.14.2/topics/tag" rel="noreferrer">Shiny documentation</a> does not help much either. What exactly am I supposed to put inside the tagList() function? Should I only wrap input arguments in a tagList(), like shown in all examples and video tutorials, or can I put other elements in there, such as a sidebarPanel()?</p>
