Related Auto Complete Component
Renders the relationship between the page's main mediatype and a related mediatype as an autocomplete-style picker — typing in the input filters related records, and selection adds the chosen record(s) to the relationship.
Smallest and lightest of the three related-record components — use when the operator only needs to set the identity of the related record, not its fields. For a form-style interface use the Related Form Component; for a list-style interface use the Simple Related List.

Simple Related List, Related Form Component, Ordered Related List — the four related-record components share most semantics; choose based on the UX you want.
Configuration Keys
These are all available Configuration Keys for the Related Auto Complete Component.
The configuration must be inserted into the database table:
MIB3UX_PAGE_COMPONENT_CONFIGURATIONS
ALLOW_BULK_EDIT
Boolean value;
True: default value; Enable page item to be bulk edited
False: disable component Bulk edition
ALLOW_EDIT
Boolean value;
True: default value; Enable page item to be edited
False: disable component edition disregarding the user permissions
ALLOW_REMOVE
Boolean value;
True: default value; Enable page item to be deleted
False: disable component deletion disregarding the user permissions
HIDE_BULK_EDIT
Boolean value.
True: bulk-edit is disabled for this component.
False (default): bulk-edit is enabled for this component.
Details: This flag is used when the main mediatype on the page can be bulk-edited but the related component should not be.
MEDIATYPE
The value is a name of a meditype.
This configuration defines which mediatype is loaded in the component.
PARENT_MEDIATYPE
Value is a Mediatype name;
It is used to link the main mediatype from the page with the mediatype of related component;
Ex:
Having a Movie page with a MMedias related form component.
Into the MMedias related form configuration, may be used the following:
CONFIGURATION_KEY: PARENT_MEDIA_TYPE
CONFIGURATION_VALUE: MVP_MOVIES
Now, the mmedias items are linked with the main mediatype (movies) item.
READONLY
Boolean value;
True: force a component be read only disregarding the user permissions
False: default value; component behavior regards only user permissions
TITLE
The value is the name of the component rendered in the page.

Custom backend, core React. Same shape as Simple Related List with
Autocomplete: true in the schema's configuration, and
COMPONENT_VIEW_TYPE = 'relatedList'. The widget renders the chip-input
- async typeahead automatically; your backend only needs to expose the mediatype lookup for the typeahead's search.
