Thread:Extension talk:Semantic Forms Inputs/Installed, but doesn't seem to take effect/reply (3)

On further investigation, the Javascript error only occurs when I 'Preview' a form - it isn't caused by the SFI field, and when I just save the form, with the field, without preview, there are no Javascript errors, and the datepicker and datetimepicker work! However, the menuselect field, which is what I really want to use, still doesn't. When the extension page says This does currently only work in the development version on SVN. does that refer to the whole menuselect field, or just linking internally?
