In my settings tab, how can I implement a toggler that allows you to select multiple car makes for search?

OBJECTIVE: So you are searching for cars …You want to specify a make or collection of makes that will only show in the results.

IMPLEMENTATION: Among other settings like radius and body type, i want to be able to set an object on scope that holds true/false for certain car manufacturers (audi, bmw, etc) to show up in results.

So I need a line item that says “makes” that pops open a new scrollable listing of checkbox options

Basically I need to know how to pop open this new pane from the settings menu.
