selectInput within table not rendering properly

I have tried to insert a selectInput (or selectizeInput) element inside a data frame and render it using the function DT::renderDataTable with the option escape = F. However, it seems that selectInput (or selectizeInput) rendered in this way does NOT allow me to search the entries, which is annoying, since I have a large number of entries. Any ideas on how to fix this?

Here is a reproducible example:


ui = fluidPage(DT::dataTableOutput("table_with_select"))

server = function(input, output, session) {
    my_table = reactive({
        df = data.frame(A = 1:5, B = 6:10)
        df[1, 1] = selectInput("select_inside_table", label = "Choose a letter", choices = c("A", "B", "C")) %>% as.character()
    output$table_with_select = DT::renderDataTable(my_table(), escape = F)

shinyApp(ui, server)
