Hey @hazelngan, I reopened this PR since the latest commit went unreviewed and introduced critical issues that need fixing before merging.

1. Blocker: The in_kind_donation_items column doesn't exist
   A previous commit deleted it and, in turn, left only donation links. Your latest commit reintroduced in-kind donation items, but there is no storage for it. You may not see the issue since your database had the column leftover from the past commit, but it currently raises an error on most pages of the site.

2. The item selection also bypasses strong parameters. It's unvalidated user content on a public nonprofit profile; this is dangerous. Make sure it intersects against the whitelist of IN_KIND_DONATION_ITEMS items.

3. Items are matched by exact display string; it is brittle, and any change or update for in-kind item names results in it breaking. Use either a table or stable key with display labels. Look at Cause/Service/BeneficiarySubcategory tables for this pattern.

4. You left the \A-\s* strip from the previous implementation, but your new code never introduces dashes as it did before, meaning this is dead code. Please remove it.

5. Make sure to add this new in-kind donation checkbox list to the admin panel, so admin users can backfill, edit, and help out organizations who may struggle adding their own items.

Make sure you run rubocop so the CI flag clears your changes
