Hi, I tried the new optgroup feature that way, and it is not working:
The optgroup is rendered as an "undefined" block.
According to that blog post, you supports dropdownlist option group.
But... for now, we are unable to sort them in "our" order, that is not alphabetical, from data source.
Also, we are unable to load them directly from the "html source" (select / optgroup / option)...
To be clear, we have 3 groups, and the name of these groups have nothing to do with alphabetical order. Also, our customer can change its UI Language, so that text can change when our user change its ui language. But, the logical order or the groups must stay the same, even if they are displayed in french, english, spanish, ...
Do you have plans to supports the option groups directly from the "<select>" source?
Or to "correctly" allow us to load them from data source, by providing a third "field" that allow us to manage order, independent of the displayted text?
