There are many features available in FormSketch to make your mapping much easier and more streamlined. One of these is the ability to arrange elements that may overlap one another on a map, so that you can have those with the higher priority to display over top of others.
In order to do this, select the arrow tool in the top toolbar, and then select the element you would like to arrange. Then you can use the Arrange functions available in that top top toolbar to adjust the element to where you would like it to be displayed.
The options available in the toolbar are: Bring to Front, Bring Forward, Send Backward, Send to Back.
Bring to Front and Send to Back will move the element so that it above or below all the elements in the man. Whereas Bring Forward and Send Backward will only move the element above or below one element with each click / tap.
