Ruby on rails docs says you can add html options to tag helpers. The code below is not working. My select box cannot shown disabled. Is there anybody knows why?

<%= form.fields_for :journal_doc_analytics do |analytics| %>
    <div style="border: 2px solid red">
    <div class="field">
      <%= analytics.label :select_personel %>
      <%= analytics.collection_select :personel_id, Personel.all, :id, :name_with_initial, disabled: true %>      
    </div>

I also tried to write like

<%= analytics.collection_select :personel_id, Personel.all, :id, :name_with_initial, options = {disabled: true} %>

Or

<%= analytics.collection_select :personel_id, Personel.all, :id, :name_with_initial, html_options={disabled: true} %>

https://edgeapi.rubyonrails.org/classes/ActionView/Helpers/FormBuilder.html#method-i-collection_select

Generated HTML code doesn't include disabled option. See below. [1]: https://i.stack.imgur.com/HuIWE.jpg Any ideas will accepted.

TLDR:

invoke the function like that (note the additional {})

<%= analytics.collection_select :personel_id, Personel.all, :id, :name_with_initial, {}, disabled: true %>

Explanation:

So this one was a bit tricky. From the docs you can see that the function accepts following params:

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

You are invoking the function like that:

<%= analytics.collection_select :personel_id, Personel.all, :id, :name_with_initial, html_options={disabled: true} %>

so if you look closely at the params, the html_options should be the last param that is passed and before it there is options param. So all the time you were passing disabled: true as options instead of html_options
