Hello,

Firstly, you should not use isolate:true for such context as richselect’s popup looses its position: http://webix.com/snippet/bb38b680

And secondly, it is still not possible to implement such functionality due to the default behaviour of popup editor - any click outside the editor or its popup stops editing of the master component (saves editor value and closes the editor).

You may consider editing date and time periods in separate columns.

Thanks Helga.
I think this feature is useful, could you add it to webix roadmap?
