There have been many attempts to do this - all have failed
But yes we should have a way of dealing with it

I stumbled upon this closed Issue: #7594

when setting up a module article category the dynamic way, when empty it
still occupies the module position.
Could this be solved by something as simple as:

If is not empty then continue what you wanna do...

I don't know if something like that would be possible. If so, it would be
possible to include or exclude some like that in your template.. just like
the countmodules..

This is an alternative to trying the "fix" countModules() which requires a B/C break

The alternative is not difficult to implement, and can be very performance wise too, it would look like:

<jdoc:addclass type="modules" name="position-7" yclass="p7" nclass="np7" />
<jdoc:addclass type="modules" name="position-8" yclass="p8" nclass="np8" />

e.g.

<div id="sidebar" class="
  <jdoc:addclass type="modules" name="position-7" yclass="span3" nclass=""/>
">
...
<main id="content" role="main" class="
  <jdoc:addclass type="modules" name="position-7" yclass="p7" nclass="np7"/>
  <jdoc:addclass type="modules" name="position-7" yclass="p8" nclass="np8"/>
">

If the position has non empty modules,

• then we replace with yclass
• otherwise we replace with nclass

Of course i do not mean strip tags like <p></p> that is totaly the responsibility of the module !

I am closing this at this time as all attempts at "fixing" this have failed and we cant introduce a b/c change for this
