Improves application performance when large amount text is passed to text area. Works great with valueButton.

pickCheckboxInput and vsCheckboxInput - make selection in many groups at once

container + grid - responsive layouts with CSS Container Queries

Build responsive layouts that adapt based on the container’s own dimensions rather than the viewport using CSS Container Queries and CSS Grid Layout. Combine container() with condition() to define CSS rules at different breakpoints, and use grid() / grid_item() as composable helpers for CSS Grid layouts.

 container(
  name = "dashboard",
  color = "#b5c5e7ff",
  div(class = "sidebar", "Sidebar", style = "background-color:#d4f89b;") |> grid_item(area = "sidebar"),
  div(class = "main", "Main content", style = "background-color:#b5c5e7;") |> grid_item(area = "main"),
  conditions = list(
    condition(
      !!!grid(
        template_areas = list(c("sidebar", "main")),
        template_columns = "200px 1fr",
        gap = "16px"
      ), 
      `font-size` = "20px"
    ),
    condition(
      query = "width < 700px",
      !!!grid(
        template_areas = list(c("sidebar"), c("main")),
        gap = "12px"
      ), 
      `font-size` = "12px"
    )
  )
)

Key features: - container() - wraps elements with container-type / container-name for CSS Container Queries - condition() - defines CSS rules for a specific container query (or unconditionally when query = NULL); supports .extra_css for targeting child selectors - grid() - generates CSS Grid properties (template_areas, template_columns, auto_fill, etc.) as a named list for splicing into condition() via !!! - grid_item() - pipe-friendly helper to set grid-area, grid-row, grid-column on individual elements

See examples/container.R for a full demo app with nested containers, auto-fill grids, and explicit row/column spanning.
