Using the Fitment Editor

The fitment editor is where you assign compatible vehicles to a product. It features a 6-stage cascade selector and a rules management table.

The Cascade Selector

The selector works in stages — each selection narrows down the next:

Brand — Select the vehicle manufacturer
Model — Select the model (filtered by brand)
Platform — Select the platform code (filtered by model)
Year — Select the year range (filtered by platform)
Variant — Optionally select a specific variant
Engine — Optionally select a specific engine

You don't need to fill all stages. For example, selecting just Brand + Model + Year range will add all matching vehicles.

Adding Vehicles

Make your selections in the cascade selector
Click Add Vehicle (or press Enter)
The matching vehicles are added to the rules table
A preview shows how many vehicles will be added before you confirm

Quick-Add Mode

Enable Quick-Add mode (toggle at the top) to keep the selector open after adding a vehicle. This is useful when adding many vehicles in sequence — the selector retains your previous selections.

The Rules Table

Below the selector, a table shows all assigned vehicles:

Column	Description
Brand	Vehicle manufacturer
Model	Model name
Variant	Specific variant
Platform	Platform code
Year Range	Production years
Engine	Engine description
KType	TecDoc reference number

Managing Rules
