This program allows fort he selection of many files from a folder. Is there any way to deselect the selected files? For example, I select some file I do not really want to select and I need to undo the selection.
Hi, just to check: do you mean giving the user less choices to choose from or letting the user undo the selection? If you mean the later, they can do this by clicking something they've already selected again.
Yes. it works for single selection, but I cannot get it to work for multiple selections? Is there any thing else I should include in the selectInput statement?
Hi I'm sorry, I'm not entirely sure I understand. Did you try the example(s) in the link? If you haven't, could try this first?
In my experience, for the "No choose prompt, multiple" Select example, I can select many options and deselect them all one by one. Similarly, in the Selectize example, I can select many options and deselect by clicking the option(s) again and pressing delete. This time though, if I also press Alt or Shift at the same time, I can select multiple options before pressing delete. I use a mac, so the keys might be different if you use something else.
