Required Field on collection_select type field

I have a form with a simple text field where I require the form to be filled out:

<%= f.text_field :email, :required => true %>

The next field is a collection_select type where I want to force the user to select a choice. I tried:

<%= f.collection_select(:list_ids, List.where(user_id: current_user), :id, :name, {}, {multiple: true}), :required => true %>

which gives me the error:

syntax error, unexpected ',', expecting ')' ..., :name, {}, {multiple: true}), :required => true );@output_... ... ^

Without the :required => true option the code works fine. How do I force a selection by the user in this case? Thanks

<%= form.collection_select :msr_cd, 
    @msrs, :msr_cd, :msr_cd,
      {multiple: false, required: true},
      data: { placeholder: "Select Measure" }, 
      class: "form-control col-sm-12 chosen-select"  
%>

Note:
    @msrs from the controller
    :msr_cd - option value`enter code here`
    :msr_cd - option text

We can pass the chosen select like above

Try this

<%= f.collection_select(:list_ids, List.where(user_id: current_user), :id, :name, {}, {multiple: true, required: true}) %>

Explanation:

According to the Rails documentation the syntax for the collection_select function looks like this:

collection_select(object, method, collection, value_method, text_method, options = {}, html_options = {})

As per the syntax options and html_options are hashes, so you need to enclose them in braces.

Try changing this

<%= f.collection_select(:list_ids, List.where(user_id: current_user), :id, :name, {}, {multiple: true}), :required => true %>

to this

<%= f.collection_select :list_ids, List.where(user_id: current_user), :id, :name, {}, {multiple: true, required: true} %>
