Just confirming, its expensive since it renders the yield twice, correct?
What if i did something like:
<% yield_contents = yield(:submenu)
if !yield_contents.strip.blank? -%>
<div class="submenu">
<%= yield_contents %>
</div>
<% end -%>
Would that work?
I guess I never realized that I could yield twice. Thanks for the tip. Much
appreciated.
