How Do You Do Multiple Checkbox Selection?

How can you do multiple checkbox selection for custom fields?
It appears that I can only select one checkbox at a time.
Is it possible to do multiple?

Not possible at the moment.

It would be a great help if multiple checkboxes can be developed in the next version and also numerical custom fields where the values can be sorted (like price). Marius from the old forums had done some work on this and it is available in the old forum and I believe on stackoverlow.
Please consider both for next versions. Thanks!

Navjot is currently working on translations for custom fields. After that I plan to integrate ordering.

Then we’ll see what’s next, probably new types.
