Dismissible alerts

With dismissible = TRUE you can allow the user to remove an alert. By default, alerts are dismissible, well suited for one-time messages or warnings.

alert(
  .style %>%
    background("primary"),
  "I'm around till you say goodbye"
)

Static alerts

If you do want to keep an alert or control an alert with renderUI() you can then use dismissible = FALSE.

alert(
  .style %>%
    background("warning"),
  dismissible = FALSE,  # <-
  "I'm calling attention to something, forever."
)

Contextual content

Alerts include a few contextual variations. Links and headings are both styled differently inside an alert.

alert(
  .style %>%
    background("success"),
  h5("Success!"),
  "Your results can be found",
  a(href = "#", "here")
)

If you want to avoid these automatic styles you can use tags$a, tags$h1, tags$h2, etc.

alert(
  .style %>%
    background("light") %>%
    border("dark"),
  tags$h6("Default heading"),
  h6("Alert heading"),
  hr(),
  tags$a(href = "#", "Default link"),
  a(href = "#", "Alert link")
)

Like the a() tag elements, yonder's linkInput()s also receive contextual styling.

alert(
  .style %>%
    background("danger"),
  h5("Problem"),
  hr(),
  linkInput(
    id = "rerun",
    label = "Click to run again"
  )
)
