arcgis-prolegend
In ArcGIS Pro 1.3.1, I have just looked for the ability to start legend items in a new column.
This functionality is present in ArcMap's Legend Properties on the Items tab which appears below:
Has anyone found the equivalent functionality in ArcGIS Pro, or know when it may be expected to appear?
It is not mentioned in the Work with a legend documentation.
Nor does it appear on the Element: Legend Item pane (see below)
Finally I found the answer : using the QgsLegendModelV2()class, and its functions inherited from QgsLayerTreeModel : "index(i,j)" to select each legend item and "rowcount" to obtain the rows number. All in a "for x in xrange" loop.
That gives:
for i in self.composition.items():
if isinstance(i,QgsComposerLegend):
legend = i
for i in xrange(legend.modelV2().rowCount()):
posteleg=legend.modelV2().index(i, 0)
print posteleg.data()
Best regards
Dynamic Legends were just added at 1.4!

Using ArcGIS Pro 2.3.0, youu can select 'Legend Arrangement Options':
Select 'Adjust Frame'.:
Then select the item from the legend that will go in a new column and return to the 'Element' settings, where a new option 'New Column' will have appeared. This functions like the 'Place item(s) in new column' setting in ArcMap:
