Panel with absolute positioning — absolutePanel

v1.7.4|Source: R/jqueryui.R

Description

Creates a panel whose contents are absolutely positioned.

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").

Value

An HTML element or list of elements.

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%".
