Add Attribute to Select Field in Rails

I'm using Slim Select for my select fields in my Rails 6 app. In order to allow users to select multiple options in the select, I have to add the attribute multiple to my select tag.

So it renders HTML, like: <select id="foo" multiple>.

How do I get multiple to show in the select tag?

I've read:

And I've tried:

<%= f.collection_select :foo, Tag.order(:name),:id,:name, include_blank: true, :html => 'multiple' %>

<%= f.collection_select :foo, Tag.order(:name),:id,:name, include_blank: true, input_html: { data: { multiple: "required"} } %>

<%= f.collection_select :foo, Tag.order(:name),:id,:name, include_blank: true, :html => {:multiple => true}  %>

<%= f.collection_select :foo, Tag.order(:name),:id,:name, include_blank: true, multiple: true %>

<%= f.collection_select :foo, Tag.order(:name),:id,:name, include_blank: true, :multiple => true %>

However, none of these add multiple in the select tag.

make sure :foo is an array that can save multiple ids, and put multiple: true as follow

<%= f.collection_select :foo, Tag.order(:name),:id,:name, {} , {multiple: true, class: '...'} %>
