Site prerequisites
The Recipe content type must exist, and it must have an Ingredients taxonomy
term reference field. At least one Vendor content item must exist. See
Adding a Content Type and Setting Up a Taxonomy.
Steps
In the Manage administrative menu, navigate to Content > Add content >
Recipe (node/add/recipe) to look at the content entry form that is set up by
default. Notice how you have to enter ingredients one by one, instead of having
a more compact format.
In the Manage administrative menu, navigate to Structure > Content
types (admin/structure/types). Then click Manage form display  on the
dropdown button for the Recipe content type. The Manage form display page
appears.
For the Ingredients field, select Autocomplete (Tags style) in the Widget
column.
Click Save.
In the Manage administrative menu, navigate to Content > Add content >
Recipe (node/add/recipe) to verify the changed behavior of the content
form. The Ingredients field is now a single text field that accepts multiple
values.
Create two Recipe content items (see Creating a Content Item), such as recipes for
"Green Salad" and "Fresh Carrots". Make sure all the fields have values,
including images, ingredients, and submitted by (set this to one of the Vendor
content items you created in Adding Basic Fields to a Content Type).
