Remarks

To configure a ResponsiveBox column collection, use a multiline lambda expression. In this case, a lambda parameter performs the role of a collection factory, and its Add() method adds a new item to the collection. The Add() method returns ResponsiveBoxColBuilder whose methods you can use to configure an item.

Razor C#

    .Cols(cols => {
        cols.Add(); // call methods to configure a ResponsiveBox column
        cols.Add();
    })
)
