managed metadata columns and filtering

Question

I use some term sets to be used in columns.

The term sets are hiearchically nested with several levels.

E.g.

• Machine
  • Mechanics
    • Frame
      • Bottom
      • Lid
      • Lid bolts
    • Structure
      • Plate 1
      • Plate 2
      • Fixture
  • Electronics
    • Assembly 1
      • Power supply
        • Transformer
        • Rectifier
      • CPU
    • Assembly 2
      • Storage
      • Backup storage

Users can select multiple terms out of this for every list entry. However when filtering I want that filtering will succeed if the filter selection is equal to the term but also when it's superseding it.

E.g. I want that when I filter for "Assembly 1" I get all occurrences of

• Assembly 1
• Power supply
• Transformer
• Rectifier
• CPU

is that possible? And if so, how?

Answer 1

According to my test, when we select only one root term, I don't think we can filter all the sub-terms contained in the root term.

It's necessary to choose all single terms you need, then filter the list view based on them.

If you are in the sharepoint online modern experience, it's necessary to choose all terms for filter. If you are using classic experience, we could filter the metadata column by clicking include descendants option, as shown below:
