flowLayout(..., cellArgs = list())
|...||Unnamed arguments will become child elements of the layout. Named arguments will become HTML attributes on the outermost tag.|
|cellArgs||Any additional attributes that should be used for each cell of the layout.|
Lays out elements in a left-to-right, top-to-bottom arrangement. The elements
on a given row will be top-aligned with each other. This layout will not work
well with elements that have a percentage-based width (e.g.
plotOutput at its default setting of
width = "100%").
