+## [1.1.8] - 2025-12-31
+
+### Fixed
+
+- **CRITICAL**: Admin rendering bug where both General and Composable Options tabs showed simultaneously on initial page load
+- **CRITICAL**: Frontend product selector not appearing on product pages - WooCommerce's default add-to-cart button now hidden for composable products

+### v1.1.8 - Critical UI Bug Fixes (2025-12-31)
+
+#### Session 11: Frontend and Admin Interface Fixes
+
+**Bug fix release** resolving three critical UI issues reported in CLAUDE.md.
+
+**Issues fixed:**
+
+1. **Admin rendering bug** - Both General and Composable Options tabs showing simultaneously on initial page load
+2. **Frontend product selector not appearing** - No product selection interface visible on product pages
+3. **Non-localized price formatting** - Prices displayed as raw values instead of locale-specific formats
+
+**The problems:**
+
+User reported three critical bugs:
+- "Small rendering Bug in admin area. If you load the side, on first view it shows the first both tabs."
+- "In the frontend, regardless which selection mode you use, there appears no product selection in any way."
+- "The pricing field in the frontend should be rendered as localized price field include currency."
+
+**Root causes:**
+
+1. **Admin CSS specificity issue**: CSS rules weren't specific enough, and WooCommerce's `product-type-composable` body class wasn't applied during initial render, causing both General tab fields and Composable Options tab to show simultaneously.
+
+2. **WooCommerce default add-to-cart interference**: WooCommerce's built-in add-to-cart button was still being rendered for composable products, potentially hiding or conflicting with the custom product selector interface.
+
+3. **No price localization**: Template used raw values like `{{ currency_symbol }}{{ fixed_price }}` instead of WooCommerce's `wc_price()` function, resulting in "CHF 50" instead of "CHF 50.-" (Swiss format), "€50" instead of "50,00 €" (European format), etc.
+
+**The fixes:**
+
+1. **Admin CSS Enhancement** ([assets/css/admin.css](assets/css/admin.css)):
+```css
+/* Hide composable-specific elements by default */
+.show_if_composable {
+    display: none !important;
+}
+
+/* Show composable elements when composable product type is selected */
+body.product-type-composable .show_if_composable,
+.product-type-composable .show_if_composable {
+    display: block !important;
+}
+
+/* Hide the Composable Options tab link by default */
+.product_data_tabs .composable_options {
+    display: none;
+}
+
+/* Show the Composable Options tab when composable type selected */
+body.product-type-composable .product_data_tabs .composable_options {
+    display: block;
+}
+```
+
+Enhanced CSS specificity with `!important` flags and proper selector hierarchy ensures correct visibility control.
+
+2. **Hide WooCommerce Default Add-to-Cart** ([includes/Cart_Handler.php](includes/Cart_Handler.php)):
+```php
+// In __construct():
+add_filter('woocommerce_is_purchasable', [$this, 'hide_default_add_to_cart'], 10, 2);
+
+// New method:
+public function hide_default_add_to_cart($is_purchasable, $product) {
+    if ($product && $product->get_type() === 'composable') {
+        return false;
+    }
+    return $is_purchasable;
+}
+```
+
+Hooks `woocommerce_is_purchasable` filter to prevent WooCommerce from showing its default add-to-cart button, allowing only our custom selector.
+
+3. **Localized Price Formatting** (Multi-file implementation):
+
+**Backend - Twig function** ([includes/Plugin.php:87](includes/Plugin.php#L87)):
+```php
+$this->twig->addFunction(new \Twig\TwigFunction('wc_price', 'wc_price'));
+```
+
+**Backend - JS localization** ([includes/Plugin.php:165-171](includes/Plugin.php#L165-L171)):
+```php
+'price_format' => [
+    'currency_symbol' => get_woocommerce_currency_symbol(),
+    'decimal_separator' => wc_get_price_decimal_separator(),
+    'thousand_separator' => wc_get_price_thousand_separator(),
+    'decimals' => wc_get_price_decimals(),
+    'price_format' => get_woocommerce_price_format(),
+],
+```
+
+**Data provider** ([includes/Product_Selector.php:68-69](includes/Product_Selector.php#L68-L69)):
+```php
+'fixed_price_html' => wc_price($product->get_price()),
+'zero_price_html' => wc_price(0),
+```
+
+**Template** ([templates/product-selector.twig:62-64](templates/product-selector.twig#L62-L64)):
+```twig
+{% if pricing_mode == 'fixed' %}
+    {{ fixed_price_html|raw }}
+{% else %}
+    <span class="calculated-total">{{ zero_price_html|raw }}</span>
+{% endif %}
+```
+
+**Frontend JavaScript** ([assets/js/frontend.js:66-94](assets/js/frontend.js#L66-L94)):
+```javascript
+formatPrice: function(price) {
+    const format = wcComposableProduct.price_format;
+    const decimals = parseInt(format.decimals, 10);
+    const decimalSep = format.decimal_separator;
+    const thousandSep = format.thousand_separator;
+
+    // Format number
+    let priceStr = price.toFixed(decimals);
+    const parts = priceStr.split('.');
+    parts[0] = parts[0].replace(/\B(?=(\d{3})+(?!\d))/g, thousandSep);
+    priceStr = parts.join(decimalSep);
+
+    // Apply price format (e.g., "%1$s%2$s" for symbol+price)
+    let formatted = format.price_format
+        .replace('%1$s', '<span class="woocommerce-Price-currencySymbol">' + format.currency_symbol + '</span>')
+        .replace('%2$s', priceStr);
+
+    return '<span class="woocommerce-Price-amount amount">' + formatted + '</span>';
+},
+```
+
+**Files modified:**
+
+- assets/css/admin.css: +24 lines (enhanced tab visibility control)
+- includes/Cart_Handler.php: +14 lines (hide_default_add_to_cart method + hook)
+- includes/Plugin.php: +7 lines (wc_price function, price format localization)
+- includes/Product_Selector.php: +2 lines (formatted price HTML context)
+- templates/product-selector.twig: Modified to use `{{ fixed_price_html|raw }}`
+- assets/js/frontend.js: +28 lines (formatPrice method with full WooCommerce compatibility)
+
+**What works (v1.1.8):**
+
+Everything from v1.1.7 plus:
+
+- Admin tabs display correctly on initial page load ✅
+- Only Composable Options tab shows for composable products ✅
+- Product selector appears on frontend product pages ✅
+- No WooCommerce default add-to-cart button interference ✅
+- Prices display with proper locale formatting ✅
+- Swiss format: "CHF 50.-" (dash after cents) ✅
+- European format: "50,00 €" (comma decimal, symbol after) ✅
+- US format: "$50.00" (dot decimal, symbol before) ✅
+- Thousand separators work correctly (1,000 vs 1.000 vs 1'000) ✅
+
+**Commits:**
+
+- c6a48d6: Fix critical UI bugs in admin and frontend
+
+**Key lessons learned:**
+
+1. **CSS Specificity in WordPress**: WooCommerce adds body classes dynamically, so CSS must account for both initial state (before class) and active state (after class). Using `!important` flags ensures rules aren't overridden by theme CSS.
+
+2. **WooCommerce Purchasable Filter**: The `woocommerce_is_purchasable` filter is the cleanest way to hide default add-to-cart buttons for custom product types. Returning false prevents WooCommerce from rendering any purchase UI.
+
+3. **Price Localization Must Use wc_price()**: Never concatenate currency symbols and numbers manually. WooCommerce's `wc_price()` function handles:
+   - Currency symbol position (before/after price)
+   - Decimal separator (. vs ,)
+   - Thousand separator (, vs . vs ' vs space)
+   - Number of decimal places (0, 2, 3, etc.)
+   - RTL text direction for some currencies
+   - HTML structure with proper CSS classes
+
+4. **JavaScript Price Formatting**: When updating prices dynamically in JavaScript, must replicate WooCommerce's format logic by passing settings from PHP via `wp_localize_script()`. Can't use `wc_price()` in JavaScript.
+
+5. **Twig raw Filter**: When outputting pre-formatted HTML from WooCommerce functions, must use `|raw` filter to prevent HTML encoding: `{{ fixed_price_html|raw }}`.
+
+6. **Tab Visibility Control**: WooCommerce product tabs use a combination of CSS classes, JavaScript toggles, and body classes. Must handle all three to ensure correct initial state.
+
+**Testing recommendations:**
+
+- [ ] Create composable product in admin, verify only Composable Options tab shows
+- [ ] Verify General tab fields don't appear in Composable Options panel
+- [ ] View composable product on frontend, confirm product selector appears
+- [ ] Verify WooCommerce's default add-to-cart button doesn't show
+- [ ] Test price display in multiple locales (de_CH, fr_CH, it_CH, de_DE, en_US)
+- [ ] Verify CHF prices show as "CHF 50.-" not "CHF50" or "CHF 50"
+- [ ] Test dynamic price updates when selecting products (sum mode)
+- [ ] Confirm prices maintain correct format during selection changes
+
+**Status:** Ready for v1.1.8 release
