Usage overview

Pick the component by field type and by where the value is entered or shown.

Where	Field or filter	Plugin	Machine name
Form	Entity reference	Tagify widget	tagify_entity_reference_autocomplete_widget
Form	Entity reference, list (integer, float, text)	Tagify Select widget	tagify_select_widget
Display	Entity reference	Tagify formatter	tagify_entity_reference_formatter
Views	Taxonomy term filter, autocomplete	Tagify (BEF)	bef_tagify
Views	Taxonomy term filter, dropdown, and other options filters	Tagify Select (BEF)	bef_tagify_select

Use the Tagify widget when the list of possible values is large or when editors need to create new terms while typing. Use Tagify Select when the field has a short, fixed list of options: all options load with the form and no autocomplete request is made.

The info label works in the Tagify widget, the Tagify formatter, and the Tagify User List and Tagify Link widgets.
