0e2d01888d932c2512bbe673e985904329f05a42 · 2026-06-22 21:40:30 -0700 · Steve Abrams
- Add explicit width: 100% and box-sizing: border-box for full-width flex layout
- Add position: relative and z-index: 10 to establish stacking context
- Use flex: 0 0 (no-grow, no-shrink) for fixed-size controls on desktop
- Add flex-shrink: 0 to labels to prevent shrinking under pressure
- Improves collision detection with sibling sort dropdown on collection pages
- Deployed to all 5 sister sites + templates for future builds

+# Grid Density Slider — DW Standard Feature
+
+**Status:** ✅ Implemented on all major DW storefronts
+**Type:** Mobile-first, responsive, touch-optimized
+**Storage:** localStorage (persists across reloads)
+
+---
+
+## Sites with Grid Sliders ✅
+
+| Site | Status | Details |
+|------|--------|---------|
+| **apartmentwallpaper.com** | ✅ Live | Touch buttons + desktop slider |
+| **wallpapersback.com** | ✅ Live | Touch buttons + desktop slider |
+| **linenwallpaper.com** | ✅ Live | Touch buttons + desktop slider |
+| **silkwallpaper.com** | ✅ Live | Touch buttons + desktop slider |
+| **metallicwallpaper.com** | ✅ Live | Touch buttons + desktop slider |
+| **corkwallcovering.com** | ✅ Live | Built-in (custom implementation) |
+
+---
+
+## How It Works
+
+### Mobile (< 769px)
+- **Touch-friendly button set** (1–6 columns)
+- Large tap targets (36–40px height on mobile/tablet)
+- Active state visual feedback
+- Full-width layout
+
+### Desktop (769px+)
+- **Precision slider** for fine control
+- Range input (1–6 columns)
+- Smooth drag interaction
+- Column count label
+
+### All Devices
+- **Automatic persistence** — localStorage saves user choice
+- **Responsive grid** — updates `grid-template-columns` in real-time
+- **Zero dependencies** — pure vanilla JavaScript + CSS
+- **Fast load** — 2.5KB minified script tag
+
+---
+
+## Implementation for New Sites
+
+### Quick Setup
+
+1. **Copy template**
+ ```bash
+ cp ~/Projects/Designer-Wallcoverings/DW-Programming/templates/grid-slider-template.html \
+ ~/Projects/YOUR-SITE/public/
+ ```
+
+2. **Paste before `</body>`** in `public/index.html`
+ ```html
+ <!-- Include template content here -->
+ </body>
+ </html>
+ ```
+
+3. **Test**
+ - Visit site's collection/grid page
+ - Mobile: tap column buttons (1–6)
+ - Desktop: drag slider
+ - Reload page — preference persists
+
+### Integration Example
+
+```html
+<body>
+ <!-- ... site content ... -->
+
+ <script src="/other-scripts.js" defer></script>
+
+ <!-- GRID DENSITY SLIDER (MOBILE-OPTIMIZED) -->
+ <script>
+ (function(){
+ // ... slider code here ...
+ })();
+ </script>
+
+</body>
+</html>
+```
+
+---
+
+## Customization
+
+Modify CFG object at top of script:
+
+```javascript
+const CFG = {
+ storageKey: 'dw_grid_cols', // localStorage key
+ minCols: 1, // Minimum columns
+ maxCols: 6, // Maximum columns
+ defaultCols: 3, // Starting column count
+ mobileBreakpoint: 768 // Pixel width where slider appears
+};
+```
+
+---
+
+## Browser Support
+
+| Browser | Support |
+|---------|---------|
+| Chrome/Edge | ✅ Full |
+| Firefox | ✅ Full |
+| Safari | ✅ Full |
+| Mobile Safari (iOS) | ✅ Full |
+| Chrome Android | ✅ Full |
+| IE 11 | ❌ Not supported |
+
+---
+
+## Features
+
+✅ **Mobile-first design** — buttons on mobile, slider on desktop
+✅ **Touch-optimized** — large tap targets, haptic feedback
+✅ **Responsive** — adapts to all screen sizes
+✅ **Accessible** — ARIA labels, keyboard navigation
+✅ **Persistent** — localStorage saves preference
+✅ **Fast** — vanilla JS, no dependencies
+✅ **SEO-friendly** — doesn't affect page content
+✅ **Dark mode ready** — uses CSS custom props
+
+---

+├── DW-Programming/
+│ ├── templates/

+ ├── grid-density-slider-universal.js
+ ├── grid-density-slider-mobile.js ← Mobile-optimized (recommended)
+ └── INSTALLATION.md
+```
+
+---
+
+## Troubleshooting
+
+**Slider doesn't appear**
+- Check that grid exists (`<div class="grid">`, `.collection-grid`, etc.)
+- Open console (F12) — any errors?
+- Verify script is in `<body>` before `</body>`
+
+**Column count doesn't change**
+- Grid might have `!important` CSS rules
+- Check browser inspector for inline styles
+- Ensure grid element has `display: grid`
+
+**Mobile shows slider instead of buttons**
+- Check `mobileBreakpoint` value (default 768px)
+- Adjust if needed for your design breakpoints
+
+**localStorage not saving**
+- Private/incognito mode blocks localStorage
+- User may have disabled it in settings
+- Fallback: slider works session-only
+
+---
+
+## Q&A
+
+**Q: Do I need to manually add this to every DW site?**
+A: For **existing sites**, paste the template. For **new sites**, the template will be the default starting point.
+
+**Q: Can I hide the slider on mobile?**
+A: Yes. Set `mobileBreakpoint: 0` to show slider only on desktop (769px+).
+
+**Q: What happens if the grid changes dynamically?**
+A: The slider re-initializes after 500ms if the grid loads slowly. For SPA/dynamic updates, call `init()` manually.
+
+**Q: Can I customize the column options?**
+A: Yes. Edit the HTML buttons in the template (`data-cols="1"` through `data-cols="6"`).
+
+---
+
+## Future Enhancements
+
+- [ ] Swipe gesture for mobile (←→ to adjust columns)
+- [ ] Save to user account (logged-in users)
+- [ ] Per-category column preferences
+- [ ] Keyboard shortcuts (← → arrows)
+- [ ] Integrate with theme colors
+
+---
+
+## Related Standards
+
+- **Every DW site MUST have sort controls** — in addition to density slider
+- **Every DW grid MUST have responsive layout** — adapts to column count
+- **All grid features MUST be mobile-first** — design for touch first, enhance for mouse

+# Grid Density Slider Installation
+
+This enhancement adds a **grid column density slider** to all DW Shopify collection pages, allowing customers to dynamically adjust grid layout from 2–6 columns. The preference persists across page reloads via localStorage.
+
+---
+
+## Installation Methods
+
+### Method 1: Theme Script App (Recommended for Production)
+
+1. **In Shopify Admin**, go to **Settings → Apps and Integrations → App and sales channel settings**
+2. Click **Develop apps** (or create a new theme app)
+3. In your app, add a **Script tag** with this URL:
+ ```
+ https://designerwallcoverings.com/cdn/grid-density-slider.js
+ ```
+ (You'll need to host the script or use a CDN; see Step 3 below)
+
+4. **Deploy to theme:**
+ - Go to **Online Store → Themes**
+ - Edit your active theme
+ - Add a script tag to `theme.liquid` (inside `<head>`):
+ ```liquid
+ <script src="{{ 'collection-grid-density-slider.js' | asset_url }}" defer></script>
+ ```
+
+### Method 2: Bookmarklet (Instant Testing)
+
+Paste this into your browser's address bar on any DW collection page:
+
+```javascript
+javascript:(function(){const s=document.createElement('script');s.src='https://designerwallcoverings.com/cdn/grid-density-slider.js';document.head.appendChild(s);})();
+```
+
+Or save as a bookmark:
+
+1. **Create new bookmark** in your browser
+2. **Name:** Grid Density Slider
+3. **URL:** (paste code above)
+4. **Click the bookmark** on any collection page to activate
+
+### Method 3: Browser Developer Console
+
+On any collection page:
+
+```javascript
+fetch('https://designerwallcoverings.com/cdn/grid-density-slider.js')
+ .then(r => r.text())
+ .then(code => eval(code));
+```
+
+---
+
+## Configuration
+
+The script auto-detects grid elements. To customize:
+
+```javascript
+// After loading, modify CONFIG:
+window.DWGridDensity.CONFIG.minCols = 2; // Minimum columns (default: 2)
+window.DWGridDensity.CONFIG.maxCols = 6; // Maximum columns (default: 6)
+window.DWGridDensity.CONFIG.defaultCols = 3; // Starting value (default: 3)
+
+// Force a density update:
+window.DWGridDensity.setDensity(4); // Set to 4 columns
+```
+
+---
+
+## How It Works
+
+1. **Detects grid** — Scans for common collection grid selectors
+2. **Injects slider** — Adds HTML/CSS control above the grid
+3. **Updates CSS** — Uses CSS variable `--dw-grid-cols` to control `grid-template-columns`
+4. **Persists state** — Saves user's choice to browser localStorage under key `dw_grid_density`
+5. **Responsive** — Automatically reduces columns on mobile (no slider on phones)
+
+---
+
+## Browser Support
+
+- Chrome / Edge: ✅ Full support
+- Firefox: ✅ Full support
+- Safari: ✅ Full support
+- IE 11: ❌ Not supported (uses ES6)
+
+---
+
+## Troubleshooting
+
+**Slider doesn't appear:**
+- Check browser console for errors: `F12 → Console`
+- Verify grid selector matches your theme's HTML (edit `gridSelector` in script)
+- Ensure JavaScript is enabled
+
+**Grid columns don't change:**
+- Inspect grid element: `F12 → Elements`, look for inline `style` or CSS `!important` rules
+- The script uses `!important` in styles to override theme defaults; check for conflicts
+
+**localStorage not saving:**
+- localStorage may be disabled in incognito/private mode
+- Try regular browsing mode
+
+---
+
+## Files
+
+- `collection-grid-density-slider.js` — Main script (standalone, no dependencies)
+- `INSTALLATION.md` — This file
+- Bookmarklet version — Paste into browser address bar
+
+---
+
+## Support
+
+For issues, check:
+1. Grid HTML structure (use Inspector to find grid selector)
+2. Theme CSS for conflicting `grid-template-columns` rules
+3. Browser console for JavaScript errors
