# Stepper
2+
3+
Steppers provide a visual representation of sequential steps, commonly used in tutorials or guides
4+
to break down processes into manageable stages.
5+
6+
By default every step title is a link with a generated anchor.
7+
But you can override the default anchor by adding the `:anchor:` option to the step.
8+

121+
122+
When using dynamic mapping, Elasticsearch automatically creates mappings for new fields by default.
123+
The documents we’ve added so far have used dynamic mapping, because we didn’t specify a mapping when creating the index.
124+
125+
To see how dynamic mapping works, add a new document to the `books` index with a field that doesn’t appear in the existing documents.
