## Z-Index Management System (2025-12-24)
A comprehensive z-index management system has been implemented to fix overlay stacking conflicts:
### The Problem:
- Modals were hiding dropdown overlays
- Context menus appeared behind modals
- Inconsistent z-index values across components
- No clear hierarchy for overlay stacking
### The Solution:
#### 1. Central Z-Index Constants (`00zindex.ts`):
Created a centralized file defining all z-index layers:
```typescript
export const zIndexLayers = {
// Base layer: Regular content
base: {
content: 'auto',
inputElements: 1,
},
// Fixed UI elements
fixed: {
appBar: 10,
sideMenu: 10,
mobileNav: 250,
},
// Overlay backdrops
backdrop: {
dropdown: 1999,
modal: 2999,
contextMenu: 3999,
},
// Interactive overlays
overlay: {
dropdown: 2000, // Dropdowns and select menus
modal: 3000, // Modal dialogs
contextMenu: 4000, // Context menus and tooltips
toast: 5000, // Toast notifications
},
// Special cases
modalDropdown: 3500, // Dropdowns inside modals
wysiwygMenus: 4500, // Editor formatting menus
}
```
#### 2. Updated Components:
- **dees-modal**: Changed from 2000 to 3000
- **dees-windowlayer**: Changed from 200-201 to 1999-2000 (used by dropdowns)
- **dees-contextmenu**: Changed from 10000 to 4000
- **dees-toast**: Changed from 10000 to 5000
- **wysiwyg menus**: Changed from 10000 to 4500
- **dees-appui-profiledropdown**: Uses new dropdown z-index (2000)
#### 3. Stacking Order (bottom to top):
1. Regular page content (auto)
2. Fixed navigation elements (10-250)
3. Dropdown backdrop (1999)
4. Dropdown content (2000)
5. Modal backdrop (2999)
6. Modal content (3000)
7. Context menu (4000)
8. WYSIWYG menus (4500)
9. Toast notifications (5000)
#### 4. Key Benefits:
- Dropdowns now appear above modals
- Context menus appear above dropdowns and modals
- Toast notifications always appear on top
- Consistent and predictable stacking behavior
- Easy to adjust hierarchy by modifying central constants
#### 5. Testing:
Created `test-zindex.demo.ts` to verify stacking behavior with:
- Modal containing dropdown
- Context menu on modal
- Toast notifications
- Complex overlay combinations
### Usage:
Import and use the z-index constants in any component:
```typescript
import { zIndexLayers } from './00zindex.js';
// In styles
z-index: ${zIndexLayers.overlay.modal};
```
This system ensures proper stacking order for all overlay components and prevents z-index conflicts.
