Hi group

I have just installed oXygen XML Editor 17 and I love it! Great work again from the guys from Syncro Soft. Thanks!

So here is my first question:

I've got a ditamap with a subjectscheme map, so my attribute values are displayed in a drop-down list in the Attributes pane. Is there a way to select multiple attribute values in this drop-down list?

​​

​Thanks​
