Props

posts : <Post>[]

posts should refer to an attribute in your block that is of type: 'array'. this is used internally by the component to update, re-order, and control deletion of posts from the selction.

postType : <String> (optional)

pass the singular name of a custom or built-in post type to limit results to that type (optional).

data <String>[] (optional)

the data prop allows you to define an array of strings that map to object keys from the REST API. (does not support nesting right now).

onPostSelect : function => <Post>[]

onPostSelect runs when a user selects a new post from the suggestion list upon typing. It returns a new array of all selected posts and should replace the data in your posts attribute.

onChange: function => <Post>[]

onChange runs when the user reorders the array of posts or removes a post from the array. it returns a new array that should replace your posts attribute.

limit: <Number> (optional)

Limit the number of posts a user is allowed to select.
