Key/value list

Description

Shows names and values in two aligned columns, e.g. a summary of a data set.

Usage

key_value(data = list(), id = NULL, classes = NULL, style = NULL)

Arguments

data	A named list or vector.
id	Optional identifier.
classes	Optional classes.
style	A style().

Value

A KeyValue widget with a reactive data field.

Choosing a key/value widget

• key_value(): a few known values shown in full, such as a summary panel. Not focusable, does not scroll; values are not wrapped.

• property_grid(): an inspector for many or arbitrary named values. Focusable and scrollable, wraps long values, formats vectors and lists compactly and accepts a format function.

• record_view(): property_grid() for exactly one record, such as the selected row of a data_table(); accepts a one-row data frame.

Examples

render_widget(key_value(list(Rows = 32, Columns = 11, Source = "mtcars")), 20, 3)
