I am working on a shiny app where users can upload their own data and get some plots and statistics back. However, I also want to include an example dataset that gets used instead if the user presses a specific button.

Create a set of radio buttons used to select an item from a list. The JavaScript library selectize.js provides a much more flexible interface compared to the basic select input. It allows you to type and search in the options, use placeholders, control the number of options/items to show/select, and so on. In Shiny, you can use the selectizeInput function to create a selectize input. If you need to represent a „None selected“ state, it’s possible to default the radio buttons to have no options selected by using selected = character(0). However, this is not recommended, as it gives the user no way to return to that state once they’ve made a selection.

1 Since Shiny hasn’t implemented this yet and if you’d like to stick to selectInput, a workaround would be using a selectInput but clears the selection everytime the user makes a choice.
