| /** | ||
| * Props | ||
| * | ||
| * options: (array of jsons) content for each box | ||
| * each json should look like { | ||
| * display: "Text to be displayed", | ||
| * (optional) value: the hidden value correlating to the display value (defaults to the index) | ||
| * } | ||
| * defaultSelected: (same type as options' value key) the option that will be default selected | ||
| * CAREFUL: if handleClick causes Radio to be re-rendered, make sure you're fine | ||
| * with this variable always being the defaultSelected | ||
| * containerStyle: (json) overrides the style on the outer container | ||
| * optionStyle: (json) overrides the style on each individual option | ||
| * selectedOptionStyle: (json) overrides the style on the selected option | ||
| * bgColor: (string) color of the non selected options | ||
| * color: (string) color of the non selected options text | ||
| * selectedBgColor: (string) color of the selected option | ||
| * selectedColor: (string) color of the selected options text | ||
| * handleClick: (func) function to be called when an option is clicked | ||
| * should have 1 parameter (value) which is the value | ||
| * (from the options prop) that is selected (defaults to index) | ||
| * allowMultipleSelected: (bool) if true, allows multiple options to be selected | ||
| * changes handle click to be called with all selected values | ||
