This change allows the wrappers to not output their rendered HTML when
when the block yields no content.
e.g. when defining an optional component :
ba.wrapper tag: :div, class: 'form-helper -message -hint' do |bb|
bb.optional :hint, wrap_with: { tag: :p }
end
and that component is not used in a template :
<%= form.input :name %>
Then the HTML output still contains the wrapper output :
<div class="form-helper -message -help"></div>
If this behaviour is not desired, then the output of the empty tags can
be disabled via the `remove_empty` option.
ba.wrapper tag: :div, class: 'form-helper -message -hint', remove_empty: true do |bb|
bb.optional :hint, wrap_with: { tag: :p }
end
The above config will not output any wrapper HTML.
