## SmartTag class

This element specifies the presence of a smart tag around one or more inline structures
(runs, images, fields,etc.) within a paragraph.
To learn more, visit the [Structured Document Tags or Content Control](https://docs.aspose.com/words/nodejs-net/working-with-content-control-sdt/) documentation article.




### Remarks

Smart tags is a kind of custom XML markup. Smart tags provide a facility for embedding
customer-defined semantics into the document via the ability to provide a basic namespace/name
for a run or set of runs within a document.

[SmartTag](./) can be a child of a [Paragraph](../../aspose.words/paragraph/) or
another [SmartTag](./) node.

The complete list of child nodes that can occur inside a smart tag consists of
[BookmarkStart](../../aspose.words/bookmarkstart/), [BookmarkEnd](../../aspose.words/bookmarkend/),
[FieldStart](../../aspose.words.fields/fieldstart/), [FieldSeparator](../../aspose.words.fields/fieldseparator/), [FieldEnd](../../aspose.words.fields/fieldend/), [FormField](../../aspose.words.fields/formfield/),
[Comment](../../aspose.words/comment/), [Footnote](../../aspose.words.notes/footnote/),
[Run](../../aspose.words/run/), [SpecialChar](../../aspose.words/specialchar/),
[Shape](../../aspose.words.drawing/shape/), [GroupShape](../../aspose.words.drawing/groupshape/),
[CommentRangeStart](../../aspose.words/commentrangestart/),
[CommentRangeEnd](../../aspose.words/commentrangeend/),
[SmartTag](./).




**Inheritance:** [SmartTag](./) → [CompositeNode](../../aspose.words/compositenode/) → [Node](../../aspose.words/node/)
