Setting up the restaurants menu form
After installing and activating the restaurants menu extension, login into your WordPress admin panel and navigate to Listings → Custom fields to create a new field.
Click the "Add new field" button and select the "Restaurant menu" field type.
After creating the field, you'll be redirected to a page to customize it's settings.
Please note: all customization settings are currently ignored because the field doesn't appear directly within the listing submission form but into a separate page.
