Step 1
First you have to create custom fields. Go to Listeo Editor → User Fields. There are two tabs for Guest and Owner as you can set those fields separately for each role.
For this guide purpose we will add VAT Number field.
Click the green button Add field, type a name and click OK, you will see box with new field and options for that field. You can switch Type of this field to dropdown, radio, checkbox or even file upload field.
Step 2
When you are ready click Save Changes and go to Listeo Editor → Registration Fields. Here you will see the field you’ve just created in the Available Fields section in the right side, you can simply drag&drop it to the fields area, and save.
That way this field will be now added to your registration form. You can change the label or set a new icon for that field.
