Filter Variable in Tags

In JENTIS, e-commerce and list-related tags include a powerful feature called the Filter Variable. This allows you to restrict tag execution to only specific data elements—typically products—based on a defined property value.

What Is the Filter Variable?

The Filter Variable is found in the configuration panel of a tag (e.g., Google Analytics 4 view_cart tag). It is typically set to evaluate the type property of product objects in the JENTIS Data Layer.

With this setting, you can filter which product objects are passed to the tag, ensuring that only those relevant to the tag's context are included.

Background: JENTIS Data Layer Behavior

Some interactions—like cartview, checkout, or productlist—may involve multiple product objects within the same page load. These are all pushed into the same state and would, by default, be visible to all tags triggered in that state.

To avoid submitting irrelevant data, the Filter Variable helps you isolate only the required product entries.

Example: Mixed Product Contexts

The following example pushes two products with different type values:

_jts.push({
  track: "product",
  type: "cartview",
  id: "123",
  name: "Baby Oil"
});

_jts.push({ track: "cartview" });

_jts.push({
  track: "product",
  type: "productlist",
  id: "456",
  name: "Baby Shampoo"
});

_jts.push({
  track: "productlist",
  listname: "related_products"
});

_jts.push({ track: "submit" });

In this case:

• Baby Oil is part of a cartview

• Baby Shampoo is part of a productlist

Applying the Filter

Let’s say you configure a GA4 view_cart tag. You only want to send products with type: "cartview".

By setting the Filter Variable to evaluate the type property and match it to cartview, only the product "Baby Oil" will be included.

This ensures:

• Clean data in your tag

• Avoidance of unrelated products being submitted

• Higher tracking accuracy for interaction-specific tags

Summary

• Use the Filter Variable to narrow tag input to relevant product types.

• This is especially useful when multiple product contexts are present on a single page.

• Always align the filter value with the type of product object your tag is designed to handle.
