## 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.
