## Adding Custom Templates (Developers)
### Method 1: Theme Override
Copy the template from the plugin to your theme and modify it:
```bash
cp wp-content/plugins/modern-cart/templates/cart/cart-item-style1.php \
wp-content/themes/your-theme/modern-cart/cart/cart-item-style1.php
```
### Method 2: Filter the Template Path
Override the base template directory to serve templates from a different plugin:
```php
add_filter( 'moderncart_set_template_path', function( $path, $template_args ) {
// Serve from your plugin's templates dir
return MY_PLUGIN_DIR . 'templates';
}, 10, 2 );
```
### Method 3: Replace a Specific Template
```php
add_filter( 'moderncart_get_template_part', function( $template, $slug, $name ) {
if ( 'cart/cart-item' === $slug && 'style1' === $name ) {
return MY_PLUGIN_DIR . 'templates/custom-cart-item.php';
}
return $template;
}, 10, 3 );
```
### Method 4: Add Content via Actions
```php
// Add content inside the cart footer
add_action( 'moderncart_slide_out_footer_content', function( $args ) {
echo '
Custom content
';
}, 20 ); // Between coupon form (25) and totals (35) — or adjust priority
```
