# sort

Please make sure you have read the Tag Syntax document and understand how tag attribute syntax works.

## Description

A Tag that sorts a List using a Comparator both passed in as the tag attribute. If `var` attribute is specified, the sorted list will be placed into the `PageContext` attribute using the key specified by `var`. The sorted list will ALWAYS be pushed into the stack and poped at the end of this tag.

Sort a List using a Comparator both passed in as the tag attribute.
