+# 0008 - Icon strategy and configuration model
+
+## Status
+
+Accepted
+
+## Context
+
+The `zhortein/datatable-bundle` already supports icons in some areas (like actions), but lacks a unified strategy.
+As more interactive features are added (sorting, filtering, exports, bulk actions), the UI needs a consistent way to render and configure icons.
+
+The goals are:
+- providing a consistent visual language;
+- keeping icon libraries optional;
+- avoiding mandatory dependencies on specific icon sets (Bootstrap Icons, FontAwesome, etc.);
+- maintaining accessibility;
+- allowing easy configuration of icon classes.
+
+## Decision
+
+The bundle will adopt a **CSS-class based icon strategy**.
+
+### Lightweight and Optional
+
+- No mandatory icon library dependency will be introduced.
+- Support for icon libraries like **Bootstrap Icons** or **FontAwesome** will be documented but optional.
+- **Symfony UX Icons** integration is considered out of scope for the first implementation but may be added later as an optional provider.
+- If no icon classes are configured, the bundle should fall back to text-only or native-like indicators where appropriate (especially for sorting).
+
+### CSS-Class Based Implementation
+
+The first implementation will rely on CSS classes. The bundle will provide a way to configure which CSS classes should be applied for specific icon keys.
+
+### Visible Labels are Required
+
+To maintain usability and accessibility, **icon-only actions are out of scope** for now.
+All actions must have a visible label. Icons are decorative and must be hidden from screen readers.
+
+### Accessibility Rules
+
+- All rendered icons must include `aria-hidden="true"`.
+- Meaningful information must never be conveyed by icons alone.
+- Labels remain the primary way to identify actions and states.
+
+## Icon Keys
+
+The following initial icon keys are defined for the bundle:
+
+| Key | Usage | Default (Bootstrap Icons suggestion) |
+|-----|-------|---------------------------------------|
+| `action_view` | View action icon | `bi bi-eye` |
+| `action_edit` | Edit action icon | `bi bi-pencil` |
+| `action_delete` | Delete action icon | `bi bi-trash` |
+| `action_create` | Create action icon | `bi bi-plus-lg` |
+| `bulk_actions` | Bulk actions dropdown/indicator | `bi bi-check2-all` |
+| `boolean_true` | Boolean true state (icon mode) | `bi bi-check-lg text-success` |
+| `boolean_false` | Boolean false state (icon mode) | `bi bi-x-lg text-danger` |
+| `sort_neutral` | Column not sorted | `bi bi-arrow-down-up small text-muted` |
+| `sort_asc` | Column sorted ascending | `bi bi-sort-up` |
+| `sort_desc` | Column sorted descending | `bi bi-sort-down` |
+| `filter` | Filter button/dropdown | `bi bi-filter` |
+| `filter_active` | Indicator that a filter is active | `bi bi-funnel-fill` |
+| `export` | Export button/dropdown | `bi bi-download` |
+| `export_csv` | CSV export action | `bi bi-filetype-csv` |
+| `export_xlsx` | XLSX export action | `bi bi-filetype-xlsx` |
+| `confirmation_warning` | Warning icon in confirmation modals | `bi bi-exclamation-triangle` |
+
+## Configuration Shape
+
+The icon strategy will be configurable through the bundle configuration.
+
+```yaml
+zhortein_datatable:
+    icons:
+        enabled: true
+        # Default icon set prefix (optional convenience)
+        # prefix: 'bi bi-'
+        mappings:
+            action_view: 'bi bi-eye'
+            action_edit: 'bi bi-pencil'
+            action_delete: 'bi bi-trash'
+            action_create: 'bi bi-plus-lg'
+            bulk_actions: 'bi bi-check2-all'
+            boolean_true: 'bi bi-check-lg text-success'
+            boolean_false: 'bi bi-x-lg text-danger'
+            sort_neutral: 'bi bi-arrow-down-up small text-muted'
+            sort_asc: 'bi bi-sort-up'
+            sort_desc: 'bi bi-sort-down'
+            filter: 'bi bi-filter'
+            filter_active: 'bi bi-funnel-fill'
+            export: 'bi bi-download'
+            export_csv: 'bi bi-filetype-csv'
+            export_xlsx: 'bi bi-filetype-xlsx'
+            confirmation_warning: 'bi bi-exclamation-triangle'
+```
+
+At the PHP level, these mappings will be available to the renderer to resolve icon classes from keys.
+
+## Implementation Direction
+
+1. Add `icons` section to the bundle configuration.
+2. Introduce an `IconResolver` or similar internal service to map keys to CSS classes.
+3. Update Twig templates to use the icon resolver.
+4. Ensure icons are wrapped in a consistent way (e.g., `<i class="{{ icon_class }}" aria-hidden="true"></i>`).
+5. Update `DatatableDefinition` to allow overriding icons per action if needed.
+
+## Consequences
+
+- Applications can easily switch between icon libraries (e.g., from Bootstrap Icons to FontAwesome) by changing the configuration.
+- The bundle remains lightweight and does not force a specific asset dependency.
+- Accessibility is preserved by requiring labels and hiding icons from screen readers.
+- Consistent visual feedback for common datatable interactions.
