Okay, here is the code I use:
The "bbcode_code" template:
<div class="code_box_wrapper MHB_wrappers">
<div class="code_box_description">{vb:rawphrase code}:</div>
<div class="code_box"><pre id="code_select" class="code_box_text" ondblclick="selectText(this.id)" title="Double-Click To Select All Text.">{vb:raw code}</pre></div>
</div>
<script>
var newid = GetNewId("code_select");
var el = document.getElementById(newid).parentNode;
el.style.maxHeight = code_height + 'px';
maxMinButton(newid,code_height,0);
</script>
The "bbcode_html" template:
<div class="code_box_wrapper MHB_wrappers">
<div class="code_box_description">{vb:rawphrase html_code}:</div>
<div class="code_box"><pre id="code_select" class="code_box_text" ondblclick="selectText(this.id)" title="Double-Click To Select All Text.">{vb:raw code}</pre></div>
</div>
<script>
var newid = GetNewId("code_select");
var el = document.getElementById(newid).parentNode;
el.style.maxHeight = code_height + 'px';
maxMinButton(newid,code_height,0);
</script>
The "bbcode_php" template:
<div class="code_box_wrapper MHB_wrappers">
<div class="code_box_description">{vb:rawphrase php_code}:</div>
<div class="code_box"><code id="code_select" class="php_code_text" ondblclick="selectText(this.id)" title="Double-Click To Select All Text.">{vb:raw code}</code><br></div>
</div>
<script>
var newid = GetNewId("code_select");
var el = document.getElementById(newid).parentNode;
el.style.maxHeight = code_height + 'px';
maxMinButton(newid,code_height,0);
</script>
The "bbcode_quote" template:
<script>
isQuote = true;
quoteLevel++;
</script>
<div class="bbcode_container">
<div class="bbcode_quote">
<div class="quote_container">
<div class="bbcode_quote_container triangle"></div>
<div class="bbcode_postedby">
<img src="{vb:stylevar imgdir_misc}/quote_icon.png" alt="{vb:rawphrase quote}" />
<vb:if condition="$show['username']">
{vb:rawphrase originally_posted_by_x, {vb:raw username}}
<vb:if condition="$postid"><a href="{vb:raw $vboptions.vbforum_url}{vb:if "$vboptions['vbforum_url']", '/', ''}showthread.php?{vb:raw session.sessionurl}p={vb:raw postid}#post{vb:raw postid}" rel="nofollow"><img class="inlineimg quote_show_post" src="{vb:stylevar imgdir_button}/viewpost-{vb:stylevar right}.png" alt="{vb:rawphrase view_post}" /></a></vb:if>
<vb:else />
<b>Quote:</b>
</vb:if>
</div>
<div class="message quote_container_outer">
<div id="code_select" class="quote_container_inner">{vb:raw message}</div>
</div>
</div>
</div>
</div>
<script>
quoteId[quote_count] = GetNewId("code_select");
var el = document.getElementById(quoteId[quote_count]).parentNode;
el.style.maxHeight = code_height + "px";
window.onload = function(){setTimeout(function(){isQuote = true;for(var n = 0;n <= quote_count;n++){maxMinButton(quoteId[n],code_height,n);};isQuote = false;},1000);};
quote_count++;
quoteLevel--;
if(!quoteLevel)
{
isQuote = false;
}
</script>
