Once you have created a Lookup, you can then add it to a form.
Instructions
Open an existing form or create a new form
Navigate to the Builder tab
Add an element to use with the lookup. In this example, we are using the Select element and all of the Custom values will need to match the row values in our lookup table.
Note: Only Text, Multi-line Text, Email, Phone Number, Barcode Scanner, Radio Button, Select, and Autocomplete elements can be used with Lookups.
Toggle on the Enable Data Lookup option and select the lookup from the drop-down
If needed, customize the Lookup button icon or text
You will now need to create elements that match the element column names in your Lookup table (in our example, that is "Location" and "Distance"). These will populate with data after the user selects an option in the "Trails" element.
