Documentation
Wrapper tag provides base class for wrapping tag. Wrapping tag which can have defined keyword arguments, keyword
arguments group in declarative way, and provide multiple steps of template rendering.
Example:

class ExampleTag(wrapper_tag.Tag):

title = wrapper_tag.Keyword(help_text=('title for example tag'))

class Meta:
template = "<div{{ title__rendered }}>{{ content }}</div>"

def render_title(self, argument, data, context):
if argument.name not in data:
return
return ' title="{title}"'.format(data[argument.name])
And then simply use tag in template:
