Populate Variable of a Multi row variable set Dependent on another variable of Catalog Item

[rohanbhatia]

I have a variable named as Product category in the catalog item which is Reference.
I have a multi row variable set, inside this I have another variable "category" which is also reference. I want to populate category same as product category when user click add button of MRVS and when pop up open up. How can i do this?

Hi @rohanbhatia 

You mean you want to bring the Product Category from the backend and display it when a user selects the product?
I don't think it's directly possible on the frontend, but it can be accessed and used from the backend.

@rohanbhatia 

so basically you can use onLoad catalog client script which Applies on Variable Set and select your MRVS

Use this logic to grab outside variable and set in Product Category

Note: I assume both the variables are referring to same table

function onLoad() {
    //Type appropriate comment here, and begin script below

    var val = g_service_catalog.parent.getValue("productCategoryVariableName"); // give the outside variable name here
    g_form.setValue('categoryVariableName', val); // give mrvs variable name here

}

If my response helped please mark it correct and close the thread so that it benefits future readers.
