radioButtons where you can select multiple buttons, just like checkboxGroupInput

[Bernhard Klingenberg]

Hi,

it would be nice to have a radioButtons UI that has the functionality of checkboxGroupInput, i.e., where you can select several radiobuttons at once instead of just a single one. (Something like radioGroupButtons.)

Or, is there a simple workaround that replaces the checkboxes that appear with checkboxGroupInput with buttons? 

Thanks,

Bernhard

The distinguishing characteristic of radio buttons, is that they only let you choose one thing. What's wrong with the checkboxes? What kinds of choices are you trying to present?

There is nothing wrong, I just find them aesthetically more pleasing. (Plus, I have several other (single) radioButtons in my app, so it would be more uniform, but that is a small point.)

I wasn't aware that (even outside of shiny?) those round buttons automatically imply that only a single choice can be made.

Thanks!

Yep, radio buttons are a longstanding UI convention, followed by every UI toolkit I can think of since the earliest versions of Windows and Mac OS.

Here's a pretty good summary:
