Selectable bug

[mitchiru]

When I have a 1-n relation to be visualized by md-checks, I want to have the record to be the value in order to use standard ds. there is no proper option to use
optionValuePath='content'
optionLabelPath='content.name'

I would suggest following improvement to addon/components/selectable-item-group.js

if (valuePath && labelPath) {
return A(
content.map(el => {
return { value: get(el, valuePath), label: get(el, labelPath) };
})
);
} else if (labelPath) { // new option - has a label, but object == value
return A(
content.map(el => {
return { value: el, label: get(el, labelPath) };
})
);
} else {
return A(
content.map(el => {
return { value: el, label: el };
})
);
}
