Quick Pattern Map
| Pattern | Reference |
|---|---|
| Single ref on a DOM element | → patterns.md#single-ref |
| Multiple refs in one component | → patterns.md#multiple-refs |
| Refs in a list / dynamic refs | → patterns.md#list-refs |
| Callback refs (alternative approach) | → patterns.md#callback-refs |
| Ref passed to a child component | → patterns.md#forwarded-refs |
Scan Command
