selectInput(inputId, label, choices, selected = NULL, multiple = FALSE, selectize = TRUE)

Creates a drop-down list that you can use to select one or more items. The widget will pass the value of the selected items to the server as a vector of character strings (usually of length one).

Arguments

inputId The name to use to look up the value of the widget (as a character string)

label A label to display above the drop-down box

choices A list of values. The widget will include a menu option for each value of the list. If the list has names, these will be displayed in the drop down menu. Otherwise the values themselves will be displayed.

selected The value(s) that should initially be selected. Defaults to the first value, or no values if multiple = TRUE.

multiple TRUE if the user is allowed to select multiple values at once. FALSE otherwise.

selectize TRUE id Shiny should use selectize.js to build an enriched selection box. FALSE if Shiny should build a basic selection box.

Make this widget by copying the code in ui.R.
