We are using TMS Web Core V2.6 beta. It seems that setting property TCustomComboBox.DroppedDown to False doesn't hide the drop down list. In VCL context, setting a TComboBox's DroppedDown to False hides the drop down list of a combo box. Any ideas how to do this in Web context? We only found solutions that hide the complete control.
This is there for VCL code compatibility but is not implemented at this moment. Still, the latest time we checked, there was no reliable cross browser compatible way to programmatically close a HTML SELECT element.
