 | Placeholder text | `placeholder` | `Enter your email address here` |
 | Description text | `description` | `Upload a digitally-signed PDF file that is no more than 1GB in size.` |
 | Placeholder text | `help` | `# This is a large heading\n\nParagraph of text goes here.\n\nThe next paragraph goes here. You can even insert [links](https://sartography.com)!\n\nThis is a list:\n- Apples\n- Oranges\n- Bananas` |

+#### Dynamic labels
+
+If the text label of a field needs to change based on the value of some other field(s) in the form, you can use a Formly Javascript expression (see above). The example below uses a ternary (if/then) operator to display a different label if the field `dogName` is filled out.
+
+| Property > Id | Property > Value (example) |
+| ------------- | -------------------------- |
+| `label_expression` | `!!model.dogName ? 'How old is ' + model.dogName + '?' : 'How old is your dog?'` |
