inshiny (version 0.1.1)

inline_select: Inline select list input

Description

A select list input similar to shiny::selectInput() that can be included in an inline() wrapper.

Usage

inline_select(id, choices, selected = NULL, multiple = FALSE, meaning = NULL)

Value

An inline widget to be included in an inline() wrapper.

Arguments

id

The input slot that will be used to access the value.

choices

Vector or list of values to select from. Provide one of the following:

• Use an unnamed character vector, such as c("dog", "cat", "bee"), for the most basic case, where you have a list of strings you want the user to select from.

• Use a named character vector, such as c("Dog" = "dog", "Nice Kitty" = "cat", "Bee" = "bee") if you want the options displayed to the user (the names; here, Dog, Nice Kitty, and Bee) to differ from the values passed to Shiny (the values; here, "dog", "cat", and "bee").

• Use a named list, where each element is a "sub-list", to group the items under headings; the names at the top level of the list will be the heading titles and the "sub-lists" are the items appearing under that heading. For example, if you pass list(Mammals = c("Dog" = "dog", "Nice Kitty" = "cat"), Invertebrates = c("Bee" = "bee")) then Dog and Nice Kitty will appear under the Mammals heading, while Bee will appear under the Invertebrates heading, and the value passed to the Shiny server will be either "dog", "cat", or "bee".

selected

The initially selected option's value. If NULL, use the first item in choices.

multiple

Whether to allow multiple selections. As of inshiny version 0.1.0, the version of inline_select with multiple = TRUE looks and behaves a bit differently from the version of inline_select with multiple = FALSE. The package authors are working on eliminating this inconsistency.

meaning

A descriptive label, for people using assistive technology such as screen readers.

Examples

ui <- bslib::page_fixed(
    shiny::h1("Pet registration form"),
    inline("My ",
        inline_select("species", c("dog", "cat"), meaning = "Pet species"),
        "'s name is ",
        inline_select("name", list("Dog names" = c("Fido", "Rex"),
            "Cat names" = c("Felix", "Boots")), selected = "Rex"),
        ".")
)
