The default behavior for selectizeInput allows the user to click on a choice and delete it by hitting the Backspace or Delete key.
Is there any way of disabling that behavior?.
I have an app that allows users to add and remove groupings from the selectizeInput
via 'add' and 'remove' action buttons. I don't want users to remove choices with the selectizeInput
widget but rather by using the 'remove' action button.
Yes, use an onDelete
event and return false
:
library(shiny)
ui <- fluidPage(
selectizeInput(
inputId = 'selInput',
label = 'No deletion',
choices = state.name,
multiple = TRUE,
options = list(onDelete = I("function(value) {return false;}"))
)
)
shinyApp(ui, \(...) {
})
