Assign id to simple form collection options

Question

New developer trying to assign an different ids to Round Oval and Banana options, so can initiate action on select:

<%= f.input :content, label: 'Fruit Shape', :collection => %w[Round Oval Banana] %>

but all options always have the id 'update_content', I assume due to instance of Update.

$('#Round').on('click', function(){
    $("#round_div").show();
  })

Fails. From research I have tried:

:collection => %w[Round Oval Banana].map { |category| [category, {:id => category}]}

which generates

<select class="form-control select optional valid" name="update[content]" id="update_content" aria-invalid="false"><option value="">SELECT</option>
<option id="Round" value="Round">Round</option>
<option id="Oval" value="Oval">Oval</option>
<option id="Banana" value="Banana">Banana</option></select>

and other variations such as:

collection: [["Round", {:id => "round"}], ["Oval", {:id => "oval"}], ["Banana", {:id => "banana"}]],

but the round_div doesn't show
