Pet Accessory Specification Setup Guide

A pet accessory table should give a measured adjustment range instead of relying on breed names. This tutorial fits collars and harnesses whose size changes by variant. Use TableFlow to show the relevant dimensions and link to the measuring instructions for the exact product.

Try the storefront example

Select the three sample products. The first shows all six rows. The second has two empty fields, so those rows disappear. The third has no values, so the whole table disappears. You can also choose Missing variant values inside the example to hide only the selected variant’s missing rows.

Storefront example

Choose a sample product

The first product option shows all six specification rows.

Hide empty fields in your store

In the theme editor, open the TableFlow app embed and leave Empty value placeholder blank. These are sample products.

This example uses TableFlow storefront code with sample data and the settings below. Your theme’s fonts and available width can change the result. Example links show their destination; purchase controls use a sample cart. Use the checks below to confirm the finished setup in your store.

Build it in TableFlow

The images below show the TableFlow form code with local sample data, captured on 2026-09-07. Shopify navigation and action bars are outside the cropped area.

1. Prepare the metafields

In Shopify, open Settings → Custom data. Create the six definitions in Sample data and content as Single line text. Use Products for Closure, Attachment point, and Measurement method. Use Variants for Neck adjustment, Chest adjustment, and Strap width. Reuse an existing definition if it stores the same information.

Open your test product and enter the sample values in the product and variant metafields. Add the product tag pet-accessory-specifications to this test product, then save. We will use this tag to control where the table appears. For images of these Shopify controls, see the product metafield guide and variant metafield guide.

2. Name the specification table

In TableFlow, create a specification table. Enter Pet Accessory Specification in Table name. This name is for your admin. Leave Table ranking at 1st. Set Status to Published when you are ready to save the finished setup.

TableFlow Table name set to Pet Accessory Specification, Table ranking set to 1st, and Status set to Published — Table name identifies the table in TableFlow. The section title in the next step is the heading that shoppers see. Select the image to view it at full size.

3. Add the first row

Under Table content, enter Specifications in Section title. In the first row, enter Neck adjustment in Label and select Advance in Source. Then select Search metafields, above the Advance value field.

TableFlow Table content with Specifications as the section title, Neck adjustment as the label, and the Search metafields control above Advance value — Select Search metafields to connect this row to its variant value. Select the image to view it at full size.

4. Select the value and complete the six rows

In Search metafields, enter custom.neck_range. Select Neck adjustment with the Variant - single_line_text_field description. Select Insert in the selection window. The Advance value field will contain ::custom.neck_range.

Search metafields with custom.neck_range entered and the Neck adjustment variant metafield selected — This image shows the search field and selected result. The Insert button is in the Shopify action bar outside this crop. Select the image to view it at full size.

Select Add row and repeat this process for the other five rows in Sample data and content. Keep Source set to Advance. Match the result to the Scope column for each row. A Product result supplies a value shared by the product. A Variant result supplies a value for the selected option. The stored product or variant value supplies the storefront text; do not type the sample measurement into Advance value.

Show the completed six-row setup

Completed Pet Accessory Specification with six labels and their custom metafield references — Check the row order and metafield keys against this completed example. Select the image to view it at full size.

5. Choose which products show the table

Under Display condition, set Attribute to Tagged with and Condition to Match any. In Values, enter pet-accessory-specifications and select the matching option to add the tag. Only apply this tag to products that should use this specification table. Use your test product first.

TableFlow Display condition with Tagged with, Match any, and the pet-accessory-specifications tag selected — The tag must also be present on the Shopify product. This keeps the table limited to the intended products. Select the image to view it at full size.

6. Select the table location and save

Under Table locations, select Location 1. Leave the other locations clear for this example. Check the six rows, display condition, and Published status, then select Save in TableFlow.

TableFlow Table locations with only Location 1 selected — Use the same location number in the TableFlow app block in the next step. Select the image to view it at full size.

7. Add the table to the product template

Open the product template in the Shopify theme editor. Enable the TableFlow app embed. Clear Empty value placeholder so it is blank. This makes TableFlow hide rows with missing values and hide the whole table if every row is empty.

Add the TableFlow - Specification app block and select table location 1. Match the example settings, then save the theme. Open the tagged test product in your storefront and change its variant. Check the specification values, then clear one test value to confirm that its row disappears.

Example settings

This example uses 18 px title text, 14 px row text, 40% label width, row borders, and 5 px cell padding. Empty value placeholder is blank. Hiding starts after the storefront script loads; entering a dash in this setting keeps missing rows visible instead.
The custom-data definitions, scopes, and values below produce the example. The second sample variant has no variant metafield values.
Everyday harness: all six fields use the sample values below.
Small harness: leave Strap width and Measurement method empty. Other changes: Neck adjustment = 25 to 35 cm.
Travel harness: leave all six mapped metafields empty. The table and its heading are hidden.

Sample data and content

Use these values for a test. Replace them with checked product data, published destinations, and offers that your store can supply.

Detail	Suggested metafield key	Scope	Metafield type	Example value
Neck adjustment	custom.neck_range	Variant	Single line text	30 to 40 cm
Chest adjustment	custom.chest_range	Variant	Single line text	45 to 60 cm
Strap width	custom.strap_width	Variant	Single line text	20 mm
Closure	custom.pet_closure	Product	Single line text	Side-release buckle
Attachment point	custom.attachment_point	Product	Single line text	Back ring
Measurement method	custom.pet_measurement	Product	Single line text	Follow this product’s fit diagram

Can a breed name replace collar or harness measurements?

Neck and chest measurements describe different fit points. Keep them in separate fields and omit a field when it does not apply. A breed label can be a rough illustration, but it should not replace a measured range. Describe the closure and attachment points from the actual accessory.

Identify the fit points in the product diagram. Record the adjustment limits for each size from measured or approved data.
Create variant fields for ranges and strap width. Keep closure details shared only when all sizes use the same hardware.
Put fit ranges before materials in TableFlow. Link the measuring diagram beside the table for first-time buyers.
Preview an accessory without a chest measurement and confirm that an irrelevant empty row does not confuse the customer.

Read the TableFlow setup guide for the full app controls and placement options. Use the variant metafield guide for rows that change with an option.

Check the finished setup

Confirm that the smallest and largest adjustment values are in the same unit.
Check a size near a range boundary against the product’s fit instructions.
Verify that collar-only products do not inherit harness-specific attachment descriptions.

Common mistakes

Do not claim universal fit for a breed from a size name.
Do not describe an accessory as a restraint or protective device without the required product evidence.

Supported use

TableFlow displays the values you supply. It does not measure products or verify supplier claims. Use product fields for shared facts and variant fields for facts that change with the selected option. Confirm the app embed and table placement in your theme.

TableFlow features, current app plans, and Shopify metafield types and accepted values explain the supported setup.
