Find layers by querying groupCategories through Portal

Hi, I would like to query our portal for group items by category.

After loading the portal and finding the group by id, I am giving the group to this function as group0:

const getLayers = async (group0: any) => { let queryParams = { query: `categories: ["/Categories/CDC Social Vulnerability Index/Theme 1: Socio-economic"]`, } const { results } = await group0.queryItems(queryParams ) return results }

I have tried several iterations of this search string. If I am only searching one category level (/Categories/ALICE Households), it works , but if I go into a nested category (like Theme 1 here), it returns all of the layers in the group.

I have tried categories: and groupCategories:, with curly braces, with brackets, with no braces, just a string, with quotes and without. Has anyone had any success fetching layers that have been categorized in a portal group in a nested category schema?

With gratitude,

Michelle

Hi @MichelleStuart -

Instead of using the query property, have you tried using the PortalQueryParams categories property? This takes a string or an array of strings that can be formatted like so:

let queryParams = { categories: [ ["/Categories/Trending/New and noteworthy", "/Categories/Basemaps/Reference maps/Test category"] ] };

If attempting to get items in a subcategory, be sure to add those category folders the to full path.

Here's an example CodePen that queries two different categories that contain sub categories: https://codepen.io/laurenb14/pen/wvOYvWv?editors=1000

Hope this helps!
