Rails Categories dropdown shows an array at the end

Question

I'm creating a category menu on my app. I use the below code in my view to get unique categories to display.

<%= Listing.uniq.pluck(:category).each do |category| %>
   <%= link_to category, category_path(category: category) %>
<% end %>

If you look at the demo at mktdemo.herokuapp.com and click on the category dropdown in the navbar, you'll see the categories displayed. However, at the end, I get an array of all categories. Not sure why this is happening.

You should replace the first <%= with a <%-:

<%- Listing.uniq.pluck(:category).each do |category| %>
  <%= link_to category, category_path(category: category) %>
<% end %>

<%= causes the output to be printed, which in your case is an array.
