Multi-Level Nested Hierarchy in Power BI Treemap Without Using Drill-Down

Hello AnujSahay,

The native Microsoft Power BI Treemap only supports two hierarchy levels being shown at once:

• Group
• Details

So a setup like:

Category → Subcategory

works fine, but adding another visible nested layer like:

Category → Subcategory → Product

is not supported in the standard Treemap visual unless you use drill-down.

Docs:

• Treemaps in Power BI 
• Change how visuals interact in a Power BI report 

A few possible workarounds are:

• using a custom hierarchical Treemap visual from AppSource
• trying visuals like Decomposition Tree or Sunburst
• combining hierarchy fields into one label column (not true nesting, but sometimes helps)

For a fully expanded 3-level Treemap, a custom visual is probably the best option right now.
