How can I create a sticky cart pinned to the left menu?

Store Design

Topic summary

Goal: Implement a “sticky cart” that stays fixed in a sidebar while scrolling (intended to show items on the home page, pinned at the side), without installing an app.

Context: The poster is unsure which theme files to edit in Shopify, and mentions difficulty “querying row information” and creating objects. They referenced a Shopify Partners tutorial about a sticky add‑to‑cart on scroll and shared an illustrative image (central to understanding the intended UI).

Responses:

  • Request for the store URL (and password if not public) to review, plus a question about whether a sidebar cart already exists.
  • Suggestion to use the Pasilobus Sticky Cart app (works on any theme, includes a free plan), despite the request to avoid apps.

Status: No solution or code guidance provided yet; key details (theme, current sidebar/cart setup, and store access) are needed. The question of which files to edit and how to retrieve cart line item data remains open. Discussion is ongoing and unresolved.

Hi.
I’m a newbie, I’m having a problem with Card.
Is there a way for me to create a cart that is pinned to the left menu, which can stay the same when scrolling?
My idea is that when there are items in the cart, I will display them and pin them on the right side of the screen on the home page.
I have a problem with querying row information, and creating objects in shopify. I’m not sure which file I need to edit in “Edit code”.

I researched and read this article → " https://www.shopify.com/partners/blog/112052742-how-to-create-a-sticky-add-to-cart-button-on-scroll "

I found my idea like this picture. So how do I do them without installing an extra app ?

Hi @counter

Can you provide a link to your store please and a password if it’s not yet public?

Do you already have a sidebar with the cart in it?
