 +===== The Principle =====
 +
 +to make it happen, there are some BasicWrapper
 +An example by Oliver: [[http://forum.phpwcms.org/viewtopic.php?f=16&t=24605&start=15|Forum]]\\
 +<code html>
 +
 +        <header>
 +            <nav>{NAV_LIST_UL:BP}</nav>
 +    [HEADER]
 +            <section class="header-content">{HEADER}</section>
 +    [/HEADER]
 +        </header>
 +        <div class"main[LEFT] has-marginal-left[/LEFT][RIGHT] has-marginal-right[/RIGHT]">
 +    [LEFT]
 +            <section class="col-left">{LEFT}</section>
 +    [/LEFT]
 +            <article>
 +                {CONTENT}
 +            </article>
 +    [RIGHT]
 +            <section class="col-left">{RIGHT}</section>
 +    [/RIGHT]
 +        </div>
 +        <footer>

 +===== This also counts for CUSTOM_BLOCKS =====
 +
 +simple
 +<code html>
 +[BLOCK]<tag>{BLOCK}</tag>[/BLOCK]
 +[BLOCK_ELSE]<tag>och nö, fehlt</tag>[/BLOCK_ELSE]
 +</code>
 +
 +nested
 +<code html>
 +[BLOCK_ELSE][RIGHT]<tag>{RIGHT}</tag>[/RIGHT][/BLOCK_ELSE]
 +</code>
 +
 +===== Want some examples? =====
 +==== LEFT visible? ====
 +
 +really? Here is the first, very simple (corrected by Oliver ;) )\\
 +<code html>
 +[LEFT]
 +    <div class="col-md-3">
 +        {LEFT}
 +    </div>
 +[/LEFT ]
 +    <div class="col-md-[LEFT]9[/LEFT][LEFT_ELSE]12[/LEFT_ELSE]">
 +        {CONTENT}
 +    </div>
 +</code>
 +What does it do? Right what it should: in case {LEFT} has no content the main content will expand to 12 columns. Otherwise there is a column 3 and column 9 (bootstrap)
 +
 +
 +
 +==== LEVEL1_ID visible? ====
 +by Oliver [[forum.phpwcms.org/viewtopic.php?f=16&t=24638|Forum]]
 +<code html>
 +[LEFT]
 +    <div class="col-md-3">
 +        [LEVEL1_ID]{NAV_LIST_UL: F,  {LEVEL1_ID} , , act_path , active } [/LEVEL1_ID]
 +        {LEFT}
 +    </div>
 +[/LEFT ]
 +    <div class="col-md-[LEFT]9[/LEFT][LEFT_ELSE]12[/LEFT_ELSE]">
 +        {CONTENT}
 +    </div>
 +</code>
 +
 +==== Level there? ====
 +<code>
 +[IF_CAT:28,29,30]<!-- whatever -->[/IF_CAT]
 +[IF_NOTCAT:0,1,2]<!-- whatever -->[/IF_NOTCAT]
