Swatches and size buttons in place of the drop-downs on a product page. Picking a colour changes the main picture and the gallery.
C4D Variation Swatches & Gallery turns the drop-down menus of your variable products into swatches customers can see and click: colour dots, small images or text buttons. Pick a colour and the main gallery changes to the photos of that colour. For shops that sell in sizes, customers can add several sizes to the cart in one click.
It is free, has no photo limit, and works with block themes and classic themes.
Set a type on each attribute under Products Attributes and the drop-down becomes buttons.
Add as many photos as you like to each option in the Swatch Images box of the product editor. When a customer picks a colour, the main gallery switches to the photos of that colour. Choose a slider or grid for the thumbnails, horizontal or vertical, with zoom, a lightbox and a full-screen pan and zoom.
Show the colours under each product in the shop grid, flip the thumbnail when a customer hovers over a swatch, collapse long lists behind a “View more” link, and align the swatches left, centre or right.
Pick an attribute, for example Size, in the Variation Swatches tab of a product. Each value then gets a quantity box. A customer chooses a colour, ticks sizes S, M and L with quantities 2, 1 and 3, and adds them all with one button. Each size becomes its own cart line. It works together with C4D Buy More Save More: the quantities of all variations of one product add up toward the discount tiers.
A Pro version is available from coffee4dev.com, for shops that want more. This plugin stays free and keeps every feature it has: nothing is taken out of it or limited to make room for Pro. Pro adds two things:
Sizes, borders, shapes and colours are styled with CSS. Add your rules in C4D › Swatches Custom CSS. They are printed late in the page head, after the theme styles, so they win. The documentation lists the selectors and has copy-and-paste examples.
The documentation covers every setting, with setup guides and CSS examples. The demo store has the plugin working on sample products.
Multi Orders is chosen per product, in the Variation Swatches tab of the product editor.
C4D Product Bundles for WooCommerce: sell products together at a discount. Customers tick the items, pick sizes and colours and add the whole bundle in one click. See all plugins at coffee4dev.com.
Ask in the support forum or read the documentation. If the plugin works well on your shop, a review helps other store owners find it.
