So I have successfully implemented the React InstantSearch library in my app, and am trying to apply a filter to the refinement list (to ensure the filters that show up are relevant to the active user, and hide the ones that aren't). I have tried the below:
<RefinementList attributeName="organization" transformItems={items => items.filter(e => refineList.indexOf(e)>=0)} />
where refineList is a simple array of strings (i.e. ["A", "B", "C"])
However the RefinementList keeps showing all of the filter options, without having the "transformItems" function applied to it. Would it be that I had misunderstood how the "transformItems" works?
Documentation was quite sparse on this topic, so I'm sure it'd be helpful for many other users of the library.
The transformItems function has one parameter: items. It expects in return to have it back.
items is an array of objects with the following shape:
{
label: string,
value: array<string>,
count: number,
isRefined: bool,
}
To remove a refinement based on an array of strings you can do this:
const refineList = ['A', 'B'];
<RefinementList
attributeName="organization"
transformItems={items => items.filter(e =>
refineList.indexOf(e.label) >= 0)}
/>
