Hi, i try to make my site so customer can navigate to right products they want to use.
Here is link for website i want to make same:
So first you press car maker. Lets say Aixam
Then you deside Model. Lets say City
Then you deside model year.
Then what kind parts you are looking for
And there you find products.
I have try do this wth multi columns so you can choose like that. But when i create first site “Aixam”. to there i put multi column and link to Aixam City. i open Aixam city site. There i create multi column and will put years. But when i change to that site years where to choose, it will change years to my first site too(Aixam). So i cant make contast navigation, it just change those options to every site?
When you changing settings in Customizer, they will apply to all objects which use the same template.
So, say, you have Default page template and you create a “Multicolumn” section there – this will be shown on every page which uses Default page template.
If you want different pages to show different content you need to either create separate templates or use Dynamic sources.
Keep in mind that Shopify limits number of templates you can create.
I see what you’re trying to achieve a layered navigation where customers first pick the car maker, then the model, then year, and then filter down to the exact parts. Thats a wonderful approach for parts catalogs, but I got why you’re running into issues.
The problem with using multi-column sections across separate pages is that those sections aren’t truly independent. When you update one, Shopify applies the change globally (because it’s reusing the same section template). That’s why when you change the “years” on one brand page, it changes everywhere.
To build this the way you want, there are a couple of approaches:
Collections + filters → Create a top-level collection for each car maker (Aixam, Microcar, etc.), then use Shopify’s built-in filters (year, model, part type) so the customer can drill down without having to hardcode multi-columns.
Navigation menus → Instead of editing the theme sections, build a nested navigation (Maker → Model → Year → Parts) and link those menus to collections. This gives you independent control over each level.
Specialized apps → For very large catalogs, apps like Mega Menu builders or year-make-model (YMM) fitment apps are built exactly for this kind of use case. They save you from managing hundreds of manual pages.
Extra tip: If you plan to scale across many brands/models, it’s better to set up a structured collection system now otherwise you’ll be stuck maintaining lots of duplicated theme sections later.
Hope that helps clarify why your current setup keeps syncing across pages, and gives you a few directions to move forward, let me know if this helps?
