I want to expose some properties in the Lightning App Builder that can be set and passed to my component.
At present I don't have the proper code and so I am getting this screen.
Say I wanted to have a property called PostalCode how would I set this up within my component to provide a text box within the App Builder to set this value for the component?
Right now I have a standard Attribute for Postal Code and its not displaying a property.
<aura:attribute name="PostalCode" type="String"/>
Is there an additional attribute or completely different tag I should be using to set this up?
