# Single select and multi-select

> AI Table single select and multi-select fields: single select assigns one exclusive category per record; multi-select attaches multiple tags. Customize option colors, bulk-edit, drag to reorder, and sync options across tables.

Use the AI Table **Single select** and **Multi-select** fields to categorize or tag records. **Single select** allows one option per cell; **Multi-select** allows multiple.

**Single select** is for exclusive categories; **Multi-select** is for tagging.

For example, a **Priority** field with options P1, P2, P3 — each task gets exactly one priority — use **Single select**.

A **Review category** field with options Feature, Price, Quality, Service — each review can carry multiple tags — use **Multi-select**.
