gridPanel {imola}

Create a css grid based HTML tag

Description

Creates a HTML tag and automatically generates css style rules based on css grid, depending on the given arguments. Functionality acts as a way to generate css grid based HTML containers directly from R without the need to write any additional css rules directly.

Usage

gridPanel(
  ...,
  template = NULL,
  areas = NULL,
  rows = NULL,
  columns = NULL,
  gap = NULL,
  align_items = "stretch",
  justify_items = "stretch",
  auto_fill = TRUE,
  breakpoint_system = getBreakpointSystem(),
  id = generateID()
)

Arguments

...

Tag attributes (named arguments) and child elements (unnamed arguments or with names used in areas).

Named arguments are treated as additional html attribute values to the parent tag, unless that name is used in the areas attribute as a grid area name.

Child elements may include any combination of other tags objects, HTML strings, and htmlDependencys.

template

The name of a registered template to use as a base for the grid, or a template object from gridTemplate.

areas

A list of vectors with area names, or a vector or strings representing each row of the grid. Each element should contain the names, per row, of each area of the grid.

Expected values follow the convention for the grid-template-areas css attribute.

for example c("area-1 area-1", "area-2 area-3") and ⁠list(c("area-1", "area-1"), c(area-2", "area-3"))⁠ are both valid representations of a 2x2 grid with 3 named areas.

Supports breakpoints.

rows

A string of css valid sizes separated by a space. or a vector of sizes. For example both "1fr 2fr" or c("1fr", "2fr") are valid representations of the same 2 rows grid sizes.

Follows the convention for the grid-template-rows css attribute.

If not provided the existing space will be split equally accordingly to the areas defined in areas.

Supports breakpoints.

columns

A string of css valid sizes separated by a space. or a vector of sizes. For example both "1fr 2fr" or c("1fr", "2fr") are valid representations of the same 2 columns grid sizes.

Follows the convention for the grid-template-columns css attribute.

If not provided the existing space will be split equally accordingly to the areas defined in areas.

Supports breakpoints.

gap

The space between elements in the panel. Controls both the space between rows and columns.

Accepts a css valid value, or 2 values separated by a space (if using different values for row and column spacing).

Supports breakpoints.

align_items

The cell behavior according to the align-items css property. Aligns grid items along the block (column) axis.

Accepts a valid css align-items value (start | end | center | stretch).

Supports breakpoints.

justify_items

The cell behavior according to the justify-items css property. Aligns grid items along the inline (row) axis.

Accepts a valid css justify-items value (start | end | center | stretch).

Supports breakpoints.

auto_fill

Should the panel stretch to fit its parent size (TRUE), or should its size be based on its children element sizes (FALSE).

Supports breakpoints.

breakpoint_system

Breakpoint system to use.

id

The parent element id.

Details

Behaves similar to a normal HTML tag, but provides helping arguments that simplify the way grid css can be created from shiny.

Value

An HTML tagList.

Note

When creating responsive layouts based on css media rules, some arguments allow a named list can be passed instead of a single value.

The names in that list can be any of the breakpoints available in the breakpoint_system argument.

It is recommended to define the breakpoint system for the application globally before UI definitions, but the breakpoint_system in panel functions allows for more flexibility when reusing components from other projects.
