CheckBoxGroup missing in web Screens module

According to documentation it could be possible to add a checkboxGroup to Web gui.

<checkBoxGroup optionsEnum="com.haulmont.cuba.security.entity.RoleType"
               property="type"/>

It seems that this feature is not presented in Web module.
Does someone knows how to include it?

Hi,

What version of documentation do you use? CheckBoxGroup is available only in 7.0 release. In 6.x releases you can use OptionsGroup instead.

I found it after upgrade to version 7.0, but it is only visible in text mode as tag. Not presented in Designer Palette.
in Designer mode it is shown as unknown. Can not change properties in design mode.

Platform version platfrom-7.0.0.BETA4

Support of CheckBoxGroup will be included into the final version of the Studio 7, so you will be able to use it in UI designer.
