Hi guys,

I have a simple question regarding selectInput with multiple = TRUE. How to de-select items I selected initially? For example, I selected 3 items from the selectInput box, and later I changed my mind and only wanted 2 items. I tried and did not see a way to de-select an item.

One more question, I tried selectInput("varMisc", "Misc",choiceNames, multiple = TRUE,selected=isolate(input.varMisc)) in ui.R, but shiny complains that input is not an object. What did I do wrong?

Thanks a lot for the help!

If you are using shiny 0.9.1, selectInput() uses selectize.js by
default, and you can delete selected options using Backspace or Delete
on your keyboard, just like deleting text.

Hi,

Is there a way to supress selected choice by clicking directly on it ?

I thought about using "onclick" but I don't know how to catch the element name of a choice selected.
