I'd like to duplicate the "Undo + undo history button" in the ribbon of ArcGIS Pro using a custom sdk addin. I used these two lines in my Config.daml file :
<按钮refID = " esri_core_undoButton " / >
However, the result is not the same as the standard button with the little dropdown arrow : there are two distinct buttons instead of two in one.
Do you knwon if it is possible to group those two tools in one, as in the standard quick access tolbar ?
