Overview

Conditionally renders a ‘Yattho::BaseComponent` around the given content. If the given condition is true, a `Yattho::BaseComponent` will render around the content. If the condition is false, only the content is rendered.

Examples:

True conditional

<%# condition is true, so content will be wrapped in a <span> tag
<%= render Yattho::ConditionalWrapper.new(condition: true, tag: :span, class: "foobar")) do %>
  <%# also rendered %>
  <p class="bazboo">Some text</p>
<% end %>

False conditional

<%# condition is false so no <span> tag will render around the content (i.e. the <p> tag)
<%= render(Yattho::ConditionalWrapper.new(condition: false, tag: :span, class: "foobar")) do %>
  <%# this content will be rendered %>
  <p class="bazboo">Some text</p>
<% end %>
