Multiple select box support

How does multiple select box work in rivets? Any example would be great

Second that. Same problem has me stumped.

Any pointers would be very welcome.

select-multiple inputs now work with the standard data-value binding in 0.3.10. Values should always be an array in this case — when the input changes, it will set the attribute with the array of selected values. Likewise, setting the attribute value to an array of selected values will update the select-multiple input's options accordingly.

In the general use case most select boxes are (id, name) tuples where the ID is almost always a number.

Rivets.js expects to find a string so the following check fails where value is [1,2] and _ref is "1":

_results.push(o.selected = (_ref = o.value, __indexOf.call(value, _ref) >= 0));

It's better to check for bot strings and numbers (note: +_ref converts string to number):

_results.push(o.selected = (_ref = o.value, __indexOf.call(value, _ref) >= 0 || __indexOf.call(value, +_ref) >= 0));

I thought about converting IDs to a string array on the server side before passing it on to the client but that wouldn't be right since the JSON model representation wouldn't truly reflect the model. Since in HTML all attributes are considered strings whether you quote them or not, the model-view binder should handle it.

For now I have made the above change in my rivetsjs hoping it gets patched. If the patch doesn't get accepted, should I be looking to make the change in the adapter?

Formatters are great! Just discovered their use through your other posting and will be using those in the interim.

I know this post is old but how can I set a select to be a select-multiple and rivets recognizes that?

<select data-rv-value="building_vent.value" multiple="multiple" size="5" type="select-multiple">

That doesnt work ...
