The iterable to display as a list.

Whether or not the list should expand to fill the screen horizontally. When defaulted to False, the list is constrained to the center view area of the screen along with other text. This can be useful to keep lists aligned with the text flow.

The number of columns to display. The specified count is applicable to high-definition screens. For Lower definition screens the actual count displayed may be fewer as the layout responds to less available horizontal screen space.

The number of lines of whitespace to include between each row in the grid. Set this to 0 for tightly displayed lists.
