Editable DT Table on Shiny with Date Input or Drop Down list

Question

Need Help, I have a table with two rows namely date_time and Risk, what I want to do is User can editable directly on the output table Shiny, where:

1. for Row Date_time can be inputted directly with dateInput()
2. Row Risk can be inputted with a dropdown list with options c('high', 'medium', 'low')

Is this possible or not?

Thanks a lot for any help

library(tidyverse)
library(shiny)
library(DT)



mydata = data.frame(
  date_time = as.Date(c('30-12-2000', '30-12-1999', '30-12-1998'), format = '%d-%m-%Y'),
  risk = c('high', 'medium', 'low')
)

mydata_t <- t(mydata)


ui <- fluidPage(
  
  DTOutput(outputId = "final_tbl")
)

server <- function(input, output){
  df1 <- reactiveValues(data=NULL)
  dat <- reactive({
    mydata_t
  })
  
  observe({
    df1$data <- dat()
  })
  
  output$final_tbl <- renderDT({
    
    df1$data %>%
      datatable(editable = list(target = "cell", disable = list(columns = c(0))), options = list(paging = FALSE, searching = FALSE))
    
  })
  
  observeEvent(input$final_tbl_cell_edit, {
    info = input$final_tbl_cell_edit
    str(info)
    i = info$row
    j = info$col
    v = info$value
    
    
    df1$data[i, j] <<- (DT::coerceValue(v, df1$data[i, j]))
    ## I don't know what to write in here

  })
  
}

UPDATE :

I modified the script refer to example and it's worked now...thanks
