opts_shiny.tag: Constructive options for class 'shiny.tag'

In constructive: Display Idiomatic Code to Construct Most R Objects

Constructive options for class 'shiny.tag'

Description

These options will be used on objects of class 'shiny.tag'.

Usage

opts_shiny.tag(constructor = c("tags", "tag", "next"), ...)

Arguments

constructor	String. Name of the function used to construct the object.
...	Additional options used by user defined constructors through the opts object

Details

Depending on constructor, we construct the object as follows:

• "tags" (default): We build the object using ⁠htmltools::tags$<name>()⁠, e.g. htmltools::tags$div(), with attributes as named arguments and children as unnamed arguments. If the tag name is not a known tag or if some attributes would clash with the formal arguments of the tag function, we fall back to the "tag" constructor.

• "tag" : We build the object using htmltools::tag(). htmltools::tag() can't create an empty named list of attributes (as htmltools::tags$div() does), in this case we fall back to the "tags" constructor for known tag names, and to the list constructor otherwise.

• "next" : Use the constructor for the next supported class.

Value

An object of class <constructive_options/constructive_options_shiny.tag>
