absolutePanel: Panel with absolute positioning

In shiny: Web Application Framework for R

Panel with absolute positioning

Description

Creates a panel whose contents are absolutely positioned.

Usage

absolutePanel(
  ...,
  top = NULL,
  left = NULL,
  right = NULL,
  bottom = NULL,
  width = NULL,
  height = NULL,
  draggable = FALSE,
  fixed = FALSE,
  cursor = c("auto", "move", "default", "inherit")
)

fixedPanel(
  ...,
  top = NULL,
  left = NULL,
  right = NULL,
  bottom = NULL,
  width = NULL,
  height = NULL,
  draggable = FALSE,
  cursor = c("auto", "move", "default", "inherit")
)

Arguments

...	Attributes (named arguments) or children (unnamed arguments) that should be included in the panel.
top	Distance between the top of the panel, and the top of the page or parent container.
left	Distance between the left side of the panel, and the left of the page or parent container.
right	Distance between the right side of the panel, and the right of the page or parent container.
bottom	Distance between the bottom of the panel, and the bottom of the page or parent container.
width	Width of the panel.
height	Height of the panel.
draggable	If TRUE, allows the user to move the panel by clicking and dragging.
fixed	Positions the panel relative to the browser window and prevents it from being scrolled with the rest of the page.
cursor	The type of cursor that should appear when the user mouses over the panel. Use "move" for a north-east-south-west icon, "default" for the usual cursor arrow, or "inherit" for the usual cursor behavior (including changing to an I-beam when the cursor is over text). The default is "auto", which is equivalent to ifelse(draggable, "move", "inherit").

Details

The absolutePanel function creates a ⁠<div>⁠ tag whose CSS position is set to absolute (or fixed if fixed = TRUE). The way absolute positioning works in HTML is that absolute coordinates are specified relative to its nearest parent element whose position is not set to static (which is the default), and if no such parent is found, then relative to the page borders. If you're not sure what that means, just keep in mind that you may get strange results if you use absolutePanel from inside of certain types of panels.

The fixedPanel function is the same as absolutePanel with fixed = TRUE.

The position (top, left, right, bottom) and size (width, height) parameters are all optional, but you should specify exactly two of top, bottom, and height and exactly two of left, right, and width for predictable results.

Like most other distance parameters in Shiny, the position and size parameters take a number (interpreted as pixels) or a valid CSS size string, such as "100px" (100 pixels) or "25%".

For arcane HTML reasons, to have the panel fill the page or parent you should specify 0 for top, left, right, and bottom rather than the more obvious width = "100%" and height = "100%".

Value

An HTML element or list of elements.
