Thank you for the clarification.
The disfunction of the collapsing of the decorated dropdown is a bug and it has been logged in our feedback portal here
, so you can monitor, comment or vote on it. I have updated your Telerik points as well for the report.
Regarding your second question about the inconsistency of the UI between the decorated ASP Dropdown and the RadComboBox, our Front-End developers have been informed about that. The point is that we have recenlty upgraded to Sass styling and not all changes have been applied.
For the time being you can apply the following custom styles:
.RadForm_Default .rfdSelect_Default .rfdSelectOuter,
.RadForm_Default .rfdSelect_Default:hover .rfdSelectOuter,
.RadForm_Default .rfdSelect_Default .rfdSelectArrow span,
.RadForm_Default .rfdSelectBox_Default .rfdSelect_selected,
.RadForm_Default .rfdSelectBox_Default li:hover,
.RadForm_Default .rfdRtl .rfdSelect_Default,
.RadForm_Default .rfdRtl .rfdSelect_Default:hover,
.RadForm_Default .rfdRtl .rfdSelect_Default .rfdSelectOuter,
.RadForm_Default .rfdRtl .rfdSelect_Default .rfdSelectOuter:hover
along with the sprite which is attached to the current mail.
