AttrTag (Web API 2021)

All Superinterfaces:

DynamicTag, EnumHTMLTags, Tag
```
public interface AttrTag
extends DynamicTag
```
This interface represents a dynamic attribute on a Tag. Its dynamic content gets printed as attributes on its enclosing Tag.
The method Tag.render(com.microstrategy.web.beans.MarkupOutput, LayoutContext) should return a String, whose value is one or more HTML attributes appropriate for the enclosing HTML tag.

Since:

MicroStrategy Web 8.0.0

    An Attr tag can be used to set the value of a single attribute, or to set the value of multiple attributes simultaneosly. In the former case, this property returns the single attribute this Attr will be setting; in this case the underlying method should return a single value; in the later case the underlying method should return a Map of all the name/value pairs of dynamic attributes to append to the enclosing tag.
