 * Location: C:\xampp\htdocs\hbc\assets\css\menu_fix.css
 * Purpose: Fix dropdown menus showing all at once, add border-radius
 */

/* ===== MAIN NAVIGATION FIXES ===== */

/* Add border-radius to main navigation */
.main-navigation {
    background: rgba(255, 255, 255, 0.95);
    box-shadow: 0 2px 8px rgba(0, 0, 0, 0.1);
    border-radius: 10px;
    overflow: hidden; /* Ensure border-radius clips content */
}

/* Add border-radius to main menu items (first/last) */
.nav-menu > li:first-child .nav-link {
    border-top-left-radius: 10px;
}

.nav-menu > li:last-child .nav-link {
    border-top-right-radius: 10px;
}

/* ===== DROPDOWN MENU FIXES ===== */

/* CRITICAL: Hide all dropdown menus by default */
.dropdown-menu,
ul.dropdown-menu,
.nav-dropdown .dropdown-menu,
[class*="dropdown-menu"] {
    display: none !important; /* Force hide */
    position: absolute;
    top: 100%;
    left: 0;

    list-style: none;
    z-index: 9999;
    margin: 0;
    padding: 0;
    border-radius: 10px; /* Add border-radius */
    overflow: hidden; /* Ensure border-radius clips content */
}

/* Show dropdown ONLY on hover of parent */
.nav-dropdown:hover > .dropdown-menu,
.nav-dropdown:hover > ul.dropdown-menu,
li:hover > .dropdown-menu,
li:hover > ul.dropdown-menu {
    display: block !important; /* Force show on hover */
}

/* Ensure dropdown items look correct */
.dropdown-menu li {
    border-bottom: 1px solid #e0e0e0;
    margin: 0;
    padding: 0;
}

.dropdown-menu li:first-child a {
    border-top-left-radius: 10px;
    border-top-right-radius: 10px;
}

.dropdown-menu li:last-child {
    border-bottom: none;
}

.dropdown-menu li:last-child a {
    border-bottom-left-radius: 10px;
    border-bottom-right-radius: 10px;
}

    display: block;
    padding: 0.75rem 1rem;
    color: #1a1a1a;
    text-decoration: none;
    transition: background 0.2s ease, padding-left 0.2s ease;
}

.dropdown-menu a:hover {
    background: #e3f2fd;
    padding-left: 1.25rem;
    text-decoration: none;
}

/* Ensure parent container doesn't clip dropdowns */
.main-navigation,
.nav-menu,
.nav-menu > li {
    overflow: visible !important;
}

/* Remove any conflicting styles */
.nav-dropdown {
    position: relative;
}

/* ===== RESPONSIVE MOBILE FIXES ===== */

@media (max-width: 768px) {

    /* rev8 (2026-07-02): this file loads LAST, so it is the single authority for
       the mobile menu. We only set structural bits here; the full drill-down
       behaviour is defined in the rev8 block appended at the very end of this
       file so nothing can override it. Do NOT reveal submenus on hover here. */
    .main-navigation {
        border-radius: 0;
    }

    .nav-menu {
        flex-direction: column;
    }

    .dropdown-menu {
        position: static;
        box-shadow: none;
        background: #ffffff;
        border-radius: 0;
    }
}

/* ===== Z-INDEX HIERARCHY ===== */

/* Ensure proper stacking order */
.main-navigation {
    z-index: 1000;
}

.nav-menu {
    z-index: 1001;
}

.dropdown-menu {
    z-index: 9999;
}

/* ===== ADDITIONAL SAFETY OVERRIDES ===== */

/* Override any global dropdown styles that might interfere */
nav .dropdown-menu,
nav ul.dropdown-menu,
header .dropdown-menu {
    display: none !important;
}

nav .nav-dropdown:hover .dropdown-menu,
nav .nav-dropdown:hover ul.dropdown-menu,
header .nav-dropdown:hover .dropdown-menu {
    display: block !important;
}

/* Ensure visibility is not forced elsewhere */
.dropdown-menu[style*="display: block"] {
    /* This will be overridden by hover state */
}

/* Clean up any JavaScript-added inline styles */
.dropdown-menu {
    visibility: hidden !important;
    opacity: 0;
    transition: opacity 0.2s ease, visibility 0s linear 0.2s;
}

.nav-dropdown:hover .dropdown-menu {
    visibility: visible !important;
    opacity: 1;
    transition: opacity 0.2s ease, visibility 0s linear 0s;
}



/* =============================================================================
   MOBILE NAVIGATION — AUTHORITATIVE DRILL-DOWN (rev 8, 2026-07-02)
   This block lives at the END of menu_fix.css, which is the LAST stylesheet
   loaded by index.php (main.css, layout.css, responsive.css, menu_fix.css).
   Being last + !important makes it the final word on phones, so no other file
   can re-open the menu. Desktop (>768px) is untouched.

   STATE A collapsed (every fresh page load): only the hamburger shows; the
           9-item menu and all submenus are hidden; the page content is visible.
   STATE B menu open: tap hamburger -> the 9 items list out.
   STATE C drilled in: tap a section -> the title header, hamburger and the
           other 8 items hide; only that submenu shows, led by a [<- Back] btn.
   Navigating a submenu link loads the next page in STATE A.
