## Remarks

For example, in "\{Items.Length,-10:choose(1|2|3):one|two|three}", the [Placeholder.Alignment](/engine/6000.7/script-reference/unity/smartstrings/core/parsing/placeholder/alignment.md)s is "-10", the [Selector](/engine/6000.7/script-reference/unity/smartstrings/core/parsing/selector.md)s are "Items" and "Length", separated by the dot "Operator". the [Placeholder.FormatterName](/engine/6000.7/script-reference/unity/smartstrings/core/parsing/placeholder/formattername.md) is "choose", the [Placeholder.FormatterOptionsRaw](/engine/6000.7/script-reference/unity/smartstrings/core/parsing/placeholder/formatteroptionsraw.md) is "1|2|3", and the [Placeholder.Format](/engine/6000.7/script-reference/unity/smartstrings/core/parsing/placeholder/format.md) is "one|two|three".
