accordionEnrollOnClick {shinyGizmo} | R Documentation |
Define Enroll/Collapse trigger
Description
The function is useful if you want to override standard behavior for activating accordion item. By default accordion item is activated when its header is clicked.
In order to point the trigger to a different object (included in item's header or content) attach 'onclick = accordionEnrollOnClick()' attribute to the element. Remember to set 'enroll_callback = FALSE' to turn off standard activation behavior (click action on header).
If you want the item to be disabled (like button) when the item is enrolled please also add 'class = activatorClass' to it.
Usage
accordionEnrollOnClick(prev = FALSE)
activatorClass
Arguments
prev |
Should the current (FALSE) or previous (TRUE) item be enrolled? 'prev = TRUE' can be useful if the last accordion item is removed and we want to enroll the preceding item. |
Format
An object of class character
of length 1.
Value
'html' class string that can be used for defining i.e. 'onclick' attribute callback.
Character string - class name used for identifying accordion activator object.
Examples
if (interactive()) {
library(shiny)
activator <- function(disabled = FALSE) {
tags$button(
"Enroll", class = activatorClass, onclick = accordionEnrollOnClick(),
disabled = if (isTRUE(disabled)) NA else NULL
)
}
ui <- fluidPage(
tags$head(tags$style(
".acc-header, .acc-content {border: 1px solid; border-radius: 5px;}"
)),
accordion(
"acc",
accordionItem(
"first", div("Hello", activator(TRUE)), "There",
enroll_callback = FALSE, active = TRUE
),
accordionItem(
"second", div("General", activator(FALSE)), "Kenobi",
enroll_callback = FALSE
)
)
)
server <- function(input, output, session) {}
shinyApp(ui, server)
