Documentation

Lists items (as well as creatures) with their icon.

Append each item or creature name as a single parameter. A quantity of x, x..y, or x-y can be used as the next parameter.

Parameters

Parameter	Default	Description
iconsize	30px	size of the items
columns	1
columnWidth		set a desired width for columns. default is 15em
listtype		set to 'ol' for a numbered list, 'none' for list without bullets
showQuantityOne	false	set to `true` to also show '1 ×' if a quantity of 1 is given
showQuantityAsPerCent	false	set to `true` to also show e.g. '50%' if a quantity of 0.5 is given
noDlcIcon		set to 1 to hide the DLC-/mod-icons
mod		if set, assumes that each item in the list is a part of the specified mod, automatically adding the namespace prefix at runtime
