# INVESTIGATION - Dropdown Behind Cards Issue
Date Started: 2025-09-07
Date Updated: 2025-09-13 18:55
Status: PARTIALLY RESOLVED

## PROBLEM STATEMENT
Dropdowns from navbar menu are blocked/hidden by page elements (cards)

## INVESTIGATION FINDINGS

### Initial State (2025-09-07)
- Dropdown appeared behind cards but positioned correctly under Account button
- Previous attempts documented but unresolved

### Findings (2025-09-13)
1. **Syntax Error Found**: base.html line 20 had double quotes preventing CSS loading - FIXED
2. **Duplicate CSS Loading**: z-index-master.css loaded twice (lines 10, 12)
3. **Z-Index Values**: 
   - Dropdown has z-index: 2000 (from z-index-master.css)
   - Cards have no explicit z-index (auto)
4. **Transform Creates Stacking Context**: Cards have transform:translateY() on hover
5. **Multiple CSS Files Competing**: 4+ files setting dropdown rules with !important

### Root Cause Analysis
HYPOTHESIS: Transform property on cards creates new stacking context
- Even with z-index: 999999, dropdown appears behind cards
- Position: fixed attempted but broke positioning
- Removing transform attempted but not verified if applied

### What We Don't Know
- Actual computed z-index values (browser console blocked)
- Whether our CSS is actually being applied to elements
- Exact stacking context hierarchy

## FILES MODIFIED
1. app\templates\base.html (multiple times)
2. app\static\css\z-index-master.css (z-index changed to 2000)

## FILES CREATED (then deleted)
- dropdown_fix.css (deleted)
- dropdown_ultimate_fix.css (deleted)
- zzz_dropdown_final.css (deleted)
- dropdown_stacking_fix.css (deleted)

## FILES STILL PRESENT
- dropdown_no_transform.css (may not be working)

## TESTING BLOCKED
Unable to access browser console for computed values
