A lot of our customers' forms involving capturing comments, remarks and other information that is usually best represented with a paragraph of text. Our current free text field has previously only supported one line of text which makes this awkward and difficult to read.
Live on our designer today, you can set the "Allow Multiple Lines" property of any text field to enable this enhancement. You will also need to be running the latest iPhone/iPad and Android client, although the field is backward compatible so will revert to a single line field if the mobile client is out of date.

To achieve something like the last field, suitable for communicating lengthy instructions or presenting an agreement to the user, configure the multiline text field to be read-only with an Initial Answer. See the screenshot below for the designer configuration:
Lastly, multiline text fields get submitted exactly like normal text fields. Most connectors won't need any changes to accomodate the extra data, but if you've defined your own MS Word template you may want to provide more space for this.
