The Geometry Picker form element allows the user to draw one or more geometries on the currently selected map.
To use a geometry picker, the user clicks Add Location () and draws the location on the currently selected map. The location is listed on the form (
). If you configured the geometry picker to allow multiple locations, the user can click Add Location again and draw another location, up to the maximum number of locations. Hovering over a location in the list highlights the location on the map (
). To remove a location, the user clicks the Delete button next to the location in the list. This removes the location from the list and from the map.

The Properties table describes the properties of the
Property names in Workflow Designer's Properties panel are written using the capitalization and spacing of a title. Property names in expressions are valid JavaScript identifiers and start with a lower case letter. Expressions are case sensitive. When you access a form element property in an expression, you must use the correct capitalization.
In the table below:
If a property can be accessed in both the Properties panel and expressions, then the table gives both versions of the name.
If a property's name in the table starts with a lower case letter, then you can only access the property in expressions.
If a property's name starts with a capital letter and the table does not give a name to use in expressions, then you can only access the property in the Properties panel.
