If I use bootstrap_form_tag I get fields id starts with underscore

[shell362]

Suppose we use bootstrap_form_tag:

= bootstrap_form_tag url: categories_path_generator(@category), method: :get do |f|
  = f.select :region, StaticData::REGIONS.map.with_index {|index, region| [index, region] }, include_blank: true, selected: params[:region]

Then I got strange id of any field starts with underscore:

id="_region"

If I try to use form namespace, like this:

namespace: :ads_form

I also get strange id with double underscore in the middle:

id="ads_form__region"

I saw the code, it looks like you use form_for without model instead to use form_tag in that case. And first one makes this underscore because is waiting for model/record name.

Also I can't set id of any field manually:

f.text_field :region, id: 'ads_field_region'
or
f.text_field :region, html: { id: 'ads_field_region' }

In both cases I get id generated by form_for:

id="_region"

Bug or feature?

This is probably a bug? The name also gets surrounded by brackets.
