This is a hash-bang: #!
Hash-bangs cause havoc or a number of reasons, but there is at least one example that directly affects how Collapse-O-Matic and Collapse-Pro-Matic process URLs. Take external triggers, for example:

[expand title="question 1" id="q1"]answer 1[/expand]
[expand title="question 2" id="q2"]answer 2[/expand]
<a class="expandanchor" href="#q1">expand question 1</a>
<a class="expandanchor" href="https://spacedonkey.de/2207/collapse-pro-matic-pesky-hash-bang-urls/#q2">

So far, so good. But now, we add a link with a hash-bang:

<a class="expandanchor" href="https://spacedonkey.de/2207/collapse-pro-matic-pesky-hash-bang-urls/#!/monkey/wrench/#q2">answer 2 with a hash-bang monkey-wrench</a>

This is a bit of text that goes on for awhile just to create the illusion that there is something important to say.

What if we placed all of this inside a LI element:

Paragraphs

If the shortcode needs to be placed inside a paragraph, it’s best to use the roll-your-own method like so:

This is a paragraph of text that we just are going to throw in here. You might not like the text, as it really just rambles on and on, but it does fill the purpose of filler text. this is the <div id="target-paratest" class="collapseomatic_content_inline colomat-inline span_fix" style="display: inline;">last text in the first paragraph.
<p>This is the next paragraph of text</p>
<p>This is the final paragraph of text</p></div> <span class="collapseomatic span_fix noarrow" id="paratest" title="Read more..." tabindex="0">Read more...</span> <span id="swap-paratest" class="colomat-swap" style="display:none;">Read less...</span>
<p>Now let's see what happens.</p>

Read more… Read less…

Now let’s see what happens.

This is a follow-up post to Collapse-O-Matic > Line of Trigger Images. This time we want to have the triggers in-line but the content to be displayed below the trigger line. To do this we first must use the roll-your-own method.

Triggers:

<span class="collapseomatic" id="item_one" data-group="item-highlander">Trigger One</span> <span class="collapseomatic" id="item_two" data-group="item-highlander">Trigger Two</span> <span class="collapseomatic" id="item_three" data-group="item-highlander">Trigger Three</span>

Targets:

<div id="target-item_one" class="collapseomatic_content ">Target One</div>
<div id="target-item_two" class="collapseomatic_content ">Target Two</div>
<div id="target-item_three" class="collapseomatic_content ">Target Three</div>

The Results:

Collaspse-Commander

The same thing with collapse commander would look like this:

[expand_trig cid="2119" /] [expand_trig cid="2120" /] [expand_trig cid="2121" /]
[expand_targ cid="2119" /] [expand_targ cid="2120" /] [expand_targ cid="2121" /]

Results:
Item One Item Two Item Three

This is an example of Special Characters such as umlauts and accents in a Collapse-O-Matic Shortcode:

This is a test that features a table of content from the Table of Content plugin as well as a collapse-o-matic expand element AND a collapse-commander element.
[toc wrapping=”right”]

This is an H1 heading

This is a heading

This is the content area and it has a collapse element in it:

[expand title="This is the expand element"]...and this is the target content[/expand]

This is another h2 heading

This is an expand element element from Collapse Commander:

[expand cid="1398"/]

Test Expand Element

This is the content of the expand element

This is a third h2 element

• list item
• list item
• list item

This is another H1 heading

Fourth heading element

Fifth heading, how do you like it?

This is a quick test of the trigpos attribute.

Normally, an expand element shortcode looks and works like this:

[expand title="trigger"]hidden content[/expand]

now we are going to add the trigpos attribute:

[expand title="trigger" trigpos="below"]hidden content[/expand]

And this works exactly the same way for collapse-pro-matic, of course.

First make sure Font Awesome is installed.

<link rel="stylesheet" href="//maxcdn.bootstrapcdn.com/font-awesome/4.3.0/css/font-awesome.min.css">

Or use a plugin such as Font Awesome Icons to have it installed for you.

We are going to use the following two Font Awesome Arrows:

<i class="fa fa-arrow-circle-down"></i>

<i class="fa fa-arrow-circle-up"></i>

Next we want to create a new class for these arrows. We are going to use the name awesomearrows. The class definitions need look like so:

.collapseomatic.awesomearrows {
    background-image: none;
}
.collapseomatic.awesomearrows:before {
    font-family: FontAwesome;
    content: "\f0ab";
}
.colomat-close.awesomearrows {
    background-image: none;
}
.colomat-close.awesomearrows:before {
    font-family: FontAwesome;
    content: "\f0aa";
}

Now we need to assign the trigclass attribute our value of ‘awesomearrows’

[expand title="Trigger Text" trigclass="awesomearrows"]Target Content[/expand]
