The Documentation tab covers the settings and every screen.
OpenCart 4.1.0.4, 3.0.5.1. Tested on OpenCart 4.1.0.4 and OpenCart 3.0.5.1. The Compatibility tab lists every version range.
No. They work through OpenCart events and standard extension types (modules, order totals, themes). No core file edits, no OCMOD patches, no theme template edits, so OpenCart updates and other extensions keep working.
Yes. Every download has a package for OpenCart 4.0.2 to 4.1.x and one for OpenCart 3.0.3 to 3.0.5, and the license key works with both. Moving from OpenCart 3 to 4 later costs nothing.
One production store domain with every subdomain (www, shop., staging.), plus local development hosts such as localhost, *.local and *.test. A store on another domain needs its own license; a second-store license is 40% off. You have 14 days after installing to enter the key. 12 months of updates and support are included; after that the extension keeps working and renewals are 50% off. How licensing works
Yes. Ask for a full refund within 30 days of your first purchase, no reason needed: open a ticket or write to [email protected] with your order number. The money goes back to the card or bank account you paid with within 5 business days of approval. Refund policy
Open a ticket from your account, so your license details are attached. We answer Monday to Friday: bug reports within 1 business day, how-to questions within 2. Support policy. Not a customer yet? Ask a pre-sales question.

Side Cart Drawer turns the cart of OpenCart 4.x and 3.0.x into a drawer that slides in from the side. It opens after Add to cart and from the cart button in the header, and customers work in it without leaving the page.
The cart and checkout pages keep the standard OpenCart cart. No OCMOD, no core file edits, no outside service. One licence covers OpenCart 4 and 3.
Tested on OpenCart 4.1.0.4 and 3.0.5.1. Other 4.0.2.x to 4.1.x and 3.0.3.8 to 3.0.5.x versions are expected to work but are not tested.
kv_side_cart.ocmod.zip.kv_side_cart-oc3.ocmod.zip.The drawer works right after the install with the defaults. Open a product in your store and press Add to cart.
To change anything, open Design > Side Cart Drawer (or the edit button of the module in Extensions > Extensions > Modules). The preview on the right shows your settings with products of your catalogue.
Upload the new package the same way. Your settings stay; new settings get their defaults the next time you open the page.
Uninstalling removes the settings and the events of the extension. The cart, coupons and orders are not touched.
All settings are on Design > Side Cart Drawer.
| Setting | What it does |
|---|---|
| Status | Shows the drawer in the store. Off: the store uses its standard cart. |
| After Add to cart | Opens the drawer when a product is added, from any add to cart button. |
| Store message | Hides the standard "Success: You have added..." message when the drawer opens (the drawer shows the product instead). On OpenCart 3 it also stops the jump to the top of the product page. |
| Header cart | The cart button in the header opens the drawer instead of the drop-down. |
| More buttons | CSS selectors of other buttons that should open the drawer, one per line, for example a cart icon of your theme. Any link to #kv-side-cart opens it too. |
| Setting | What it does |
|---|---|
| Coupon | The coupon field. Shown only when the Coupon order total is enabled. |
| Free shipping goal | Off, from the Free Shipping method (Extensions > Shipping > Free Shipping, its Total), or a fixed amount. The amount is compared with the cart sub-total without tax, like the Free Shipping method does, and shown in the visitor's currency. |
| Suggestions | Up to 6 related products of the cart products that are not in the cart yet. Products with required options or a subscription plan show an Options link to their page instead of Add. |
| Setting | What it does |
|---|---|
| Side | Right or left. |
| Width | 340 to 560 px on large screens. Phones always get the full width. |
| Button colour | Checkout button, progress line, links. The text on the button turns dark on light colours so it stays readable. |
Enter your licence key from your Kavio Labs account. Without a key the extension runs as a 14-day trial. When the licence is not active, the store shows its standard cart; the settings page always works.
Any link to #kv-side-cart opens the drawer, for example in a banner or an information page:
<a href="#kv-side-cart">See your cart</a>A store address that ends with #kv-side-cart opens the page with the drawer open.
For a theme script there is window.kvSideCart.open(), .close() and .refresh().
When Login Display Prices is on (System > Settings > Option) and the visitor is not logged in, the drawer shows the products and quantities without prices and totals, like the store does.
No. The cart page and the checkout keep the standard OpenCart cart, and the drawer is not shown on them.
The drawer is its own layer and brings its own styles, so it looks the same on any theme. It opens on OpenCart's add to cart answer, so add to cart buttons of the product page, categories, modules and most themes open it. If your theme has a cart icon that is not the standard header cart, add its CSS selector under More buttons.
No. The page gets a small script and styles; the cart is loaded only when the drawer opens. Pages stay as cacheable as before.
The lines of your enabled order total extensions (sub-total, coupon, taxes, total and others), calculated by OpenCart.
The drawer shows the same warnings as the cart page: not available in this quantity, minimum quantity. Checkout rules stay OpenCart's.
The store shows its standard cart again. Nothing breaks; the settings page always works.
No. It uses OpenCart events only, so it does not change core files and updates cleanly.
