got WebRadioGroup... but why No WebCheckboxGroup?

The WebRadioGroup is a nice control for my application, but I need a group of checkboxes that are arrangeable by rows and columns…
The library only has a single check box.
Am I missing something?

Radio buttons only function in a group. Desktop apps group radio buttons by common parent. Web apps use a single control, the radio group. Radio buttons also never make sense alone.

Checkboxes do work alone, and have no required relationship to any other checkboxes. There’s no need for a checkbox group.
