Maersk Design System: Input masks
Documents input masks as controls for consistent formatted entry, including credit card grouping, copy/paste and correction requirements, hint text for complex formats, and cases where prefix/suffix or ordinary input is a better fit.
Pattern Decisions This Source Supports
| Pattern | Supported decision | Required contract | Claim note |
|---|---|---|---|
| Input mask | Choose input mask when the value has a stable, narrow structure with predictable character classes and grouping. | Typing valid characters fills the next available mask slot and inserts literal separators automatically. | Maersk supports using masks for stable expected formats while preserving copy/paste and correction, and distinguishes masks from prefix/suffix or ordinary inputs. |
| Input prefix/suffix | Choose input prefix/suffix when a common fixed symbol, unit, abbreviation, domain, or icon clarifies what the text input accepts. | The affix is visible near the input but not editable as part of the field value. | Maersk supports the boundary that prefix/suffix is preferred over a mask when a constant value is grouped with the typed value. |
