Typoscript: wrap only if content is not empty

Often i run into this problem in TYPO3 : i have to wrap a content element with Typoscript but ONLY if there is content. This has an easy solution but all too often i forget it and have to search it up again. So this time i post it here and maybe it helps others too.

subparts.col2 < styles.content.getRight
subparts.col2.stdWrap {
       wrap = 
|
       required = 1
}
