Collapse-O-Matic CSS Tricks .colomat-close

When an expand element is expanded it has the .colomat-close class assigned. This class is removed when the expand element is collapsed. So, if you want to adjust how an active/expanded trigger is displayed, simply define your custom css as follows:

/*inactive/collapsed */
.collapseomatic {

}

/*active/expanded */
.collapseomatic.colomat-close {

}

Simple Demo

Using the trigclass attribute we can further assign the design of the triggers for only specific expand elements.

CSS

.collapseomatic.my_special_class {
    color: green;
}

.collapseomatic.my_special_class.colomat-close {
    color: red;
    border: 2px dotted red;
}

Shortcode

[expand title="Trigger Text" trigclass="my_special_class"]Hidden Content[/expand]

Result

Trigger Text

Nested Collapse Elements with Highlander Grouping

Here is a typical nested collapse group with highlander grouping

[expand title="state1" id="state1" togglegroup="state-highlander"]
   [expandsub1 title="city1" id="city1" togglegroup="city-highlander"]bar1 bar2[/expandsub1]  
   [expandsub1 title="city2" id="city2" togglegroup="city-highlander"]bar3 bar4[/expandsub1]
[/expand]

[expand title="state2" id="state2" togglegroup="state-highlander"]
   [expandsub1 title="city3" id="city3" togglegroup="city-highlander"]bar5 bar6[/expandsub1]  
   [expandsub1 title="city4" id="city4" togglegroup="city-highlander"]bar7 bar8[/expandsub1]
[/expand]

Notice how the main level and nested sub-elements have their own highlander grouping defined. This makes it so the main level items do not affect the nested children expand/collapse states.
This is how it works:

state1
state2

Now to do the exact same thing using the roll-your-own method:

<div class="collapseomatic" id="state1"  title="state1" data-togglegroup="state-highlander">state1</div>
<div id="target-state1" class="collapseomatic_content">
   <div class="collapseomatic" id="city1" title="city1" data-togglegroup="city-highlander">city1</div>
   <div id="target-city1" class="collapseomatic_content">bar1 bar2</div>
   <div class="collapseomatic" id="city2" title="city2" data-togglegroup="city-highlander">city2</div>
   <div id="target-city2" class="collapseomatic_content ">bar3 bar4</div>
</div>

<div class="collapseomatic" id="state2" title="state2" data-togglegroup="state-highlander">state2</div>
<div id="target-state2" class="collapseomatic_content">
   <div class="collapseomatic" id="city3" title="city3" data-togglegroup="city-highlander">city3</div>
   <div id="target-city3" class="collapseomatic_content">bar5 bar6</div>
   <div class="collapseomatic " id="city4" title="city4" data-togglegroup="city-highlander">city4</div>
   <div id="target-city4" class="collapseomatic_content">bar7 bar8</div>
</div>

Collapse-Pro-Matic Roll Your with Scroll To Elements

The roll-your-own method has already been documented, however, what if you wanted to create your own sroll-to targets for each element? How can we do this with roll-your-own?

First we create an example using the shortcode:

[expand title="trigger text" findme="auto"]hidden content[/expand]

trigger text

Now we re-create that using the roll-your own elements:

The Trigger

<div class="collapseomatic find-me" id="my_example" title="trigger text" data-offset="-60" data-findme="auto">trigger text</div>
trigger text

The Target

<div id="target-my_example" class="collapseomatic_content ">Target Content</div>

Print-O-Matic External Buttons

this is a test element


As of version 1.6.7c we introduced a new printstyle value ‘external’ for Print-O-Matic. Now it is possible to create an external button to trigger a print in a less-hacky way. Here is an example of this works: To print the following div with an id of ‘print_me_please’:

<div id="print_me_please">This is our target print element</div>

First we create a kind of roll-your-own print trigger. The details that must be included are:

  1. a unique id
  2. a print-o-matic class such as printomatic or printomatictext
  3. a data-print_target attribute

For example:

<button id="my_print_button" class="printomatic" data-print_target="#print_me_please">Print Trigger</button>

Which will output:

The final thing we need to do is include a hidden print trigger using a print-me shortcode with the same id as our external trigger and the new external printstyle attribute. This shortcode must be placed someplace on the same page, and will load in all the required scripts and settings to make the print trigger work correctly.

[print-me id="my_print_button" printstyle="external"/]


This shortcode will not output anything to the page.
That’s it. You are done! Let us know on the WordPress Support Forum if you require any further assistance.

Collapse-O-Matic Grouping and Expandall Issues

If we set up two groups for the sole purpose of creating expand/collapse all triggers that will only expand/collapse the related group we currently have to create something like:

Science Fiction:

[expand title="Star Wars" rel="fiction"]Alliance to Restore the Republic vs. Galactic Empire[/expand]
<span class="expandall" rel="fiction">Expand All Science Fiction</span>
<span class="collapseall" rel="fiction">Collapse All Science Fiction</span>

Pure Science:

[expand title="Space Race" rel="history"]USA vs. USSR[/expand]
<span class="expandall" rel="history">Expand All Pure Science</span>
<span class="collapseall" rel="history">Collapse All Pure Science</span>

Rel Example:

Science Fiction

  • Star Wars
  • Star Trek
  • Battlestar Galactica

Expand All Science Fiction
Collapse All Science Fiction

Pure Science

  • Space Race
  • Ansari X Prize

Expand All Pure Science
Collapse All Pure Science

So this works, but what if we do NOT what the expanding of one group to automatically collapse any open items of other groups?

As of Collapse-O-matic version 1.7.1, two new attributes have been introduced to deal with exactly this issue. For the shortcode:
togglegroup='your_group_name'
and for the roll-your-own method:
data-togglegroup='your_group_name'

Science Fiction:

[expand title="Star Wars" togglegroup="fiction"]Alliance to Restore the Republic vs. Galactic Empire[/expand]
<span class="expandall" data-togglegroup="fiction">Expand All Science Fiction</span>
<span class="collapseall" data-togglegroup="fiction">Collapse All Science Fiction</span>

Pure Science:

[expand title="Space Race" togglegroup="history"]USA vs. USSR[/expand]
<span class="expandall" data-togglegroup="history">Expand All Pure Science</span>
<span class="collapseall" data-togglegroup="history">Collapse All Pure Science</span>
[expand title="Expand All" swaptitle="Collapse All" trigclass="setall" togglegroup="history"/]

Group Example:

Science Fiction

  • Star Wars
  • Star Trek
  • Battlestar Galactica

Expand All Science Fiction
Collapse All Science Fiction

Pure Science

  • Space Race
  • Ansari X Prize

Expand All Pure Science
Collapse All Pure

Expand All*

Adding Highlander Grouping:

[expand title="Monkey" togglegroup="animal" rel="animal-highlander"]monkeys are fast[/expand]
[expand title="Donkey" togglegroup="animal" rel="animal-highlander"]donkeys are strong[/expand]
<span class="expandall" data-togglegroup="animal">Expand All Animals</span>
<span class="collapseall" data-togglegroup="animal">Collapse All Animals</span>
[expand title="Expand All" swaptitle="Collapse All" trigclass="setall" togglegroup="animal"/]
  • Monkey
  • Donkey

Expand All Animals
Collapse All Animals

Expand All*
