# Expanding and Collapsing Markdown Cell

The user can expand and collapse the multiple Markdown cells based on their levels in a DS Notebook. The user can create a hierarchy of three levels using the ***Heading*** option in a Markdown cell. 

{% hint style="info" %}
*<mark style="color:green;">Please Note:</mark>*&#x20;

* *The related code cells under one Markdown will fall into the same level as the Markdown.*
* *The maximum three levels of hierarchy can be inserted for a Markdown cell using the Heading option.*&#x20;
  {% endhint %}

{% hint style="success" %}
