Collapse Pro Matic – Adding 2nd Trigger in Excerpt

Collapse-Pro-Matic version 1.3.15 introduces a couple new features dealing with secondary triggers and excerpt filtering. The following demonstrates the new features by using a filter to add a second trigger with it’s own swaptitle to all excerpts.

The following code, when placed in the child-theme’s function.php file, will add an extra ‘…read more’ trigger to the end of all excerpts. The data-swaptitle attribute defines the swaptitle for this extra trigger.

 add_filter( 'colomat_excerpt', 'my_excerpt', 10, 2 );
 function my_excerpt( $id, $excerpt ) {
     $excerpt .= ' <span class="collapseomatic" id="extra1-'.$id.'" data-swaptitle=" ...read less"> ...read more</span>';
     return $excerpt;

Then each shortcode that contains an excerpt will include the second trigger:

[expand title="I am a little tea-pot" excerpt="short and stout"]Here is my handle, here is my spout.[/expand]

And here is an example of the above in action:

I am a little tea-pot
short and stout
Here is my handle, here is my spout.

Next, what happens when there are multiple triggers with swaptitles? Let’s see.

[expand title="main trigger" swaptitle="main trigger swap" id="mankey"]this is the hidden text for this multi-target test[/expand]
<div id="extra1-mankey" class="collapseomatic" data-swaptitle="Trigger 2 Swap Titlte">Trigger 2</div>
<div id="extra2-mankey" class="collapseomatic" data-swaptitle="Trigger 3 Swap Titlte">Trigger 3</div>
main trigger
this is the hidden text for this multi-target test
Trigger 2
Trigger 3
hey dude

Guttenberg Collapse-O-Matic Image Embed

This is a little test of how to embed an image in a guttenberg expand shortcode block. The issue this aims to resolved can be found here.

since there is not an easy way to ‘insert’ an image inside a shortcode, the raw html will have to be placed. First we insert an image in a normal Gutenberg block:

Then we need to grab the html for that image by editing the block as html. The source for the above image is:

<img src="https://spacedonkey.de/wp-content/uploads/2015/06/The-Big-Lebowski-the-big-lebowski-31504499-540-720.jpg" alt="" class="wp-image-2398"/>

So we paste that in the shortcode block… so all togher it looks like:

[expand title="click to view image"] <img src="https://spacedonkey.de/wp-content/uploads/2015/06/The-Big-Lebowski-the-big-lebowski-31504499-540-720.jpg" alt="" class="wp-image-2398"/> [/expand]

And here is an example of the whole shebang in action:

Countdown Timer with Offset

This is a countdown timer that actually counts down to 15:15. However, it should display that it is actually counting down to 16:15. so an offset of + 1 hours.

So how is this done?
As of T(-) Countdown Control version 1.8.9 the target can be filtered with an offset by adding the following to the child-theme functions.php file:

add_filter( 'countdown_offset', 'my_offset', 10, 2 );
function my_offset( $id, $target_time ) {
if($id == '3411'){
$target_time = $target_time + (1 * 60 * 60);
return $target_time;

Expand/Collapse All Scroll To Current Section Test

This is a test using the ew expand_all and collapse_all callbacks to automatically scroll to the section currently being viewed. The issue is that when expand/collapse all is clicked, large amounts of content is suddenly added to–or removed from–the page. This new page length will often re-flow the page, causing the user to loose their place in the currently viewed content.

The Idea is to implement the following:
1. Create ‘section headers’ that will automatically update when the users scrolls past them.

<h2 id="section-1" class="section">Section Title</h2>

2. Add some javascript that will saved the currently viewed section id to a variable.

 jQuery(document).ready(function () {
        jQuery(document).on("scroll", onScroll);
        var currSection = null;

function onScroll(event){
        var scrollPos = jQuery(document).scrollTop();
        jQuery('.section').each(function () {
            var currElement = jQuery(this);
            if (currElement.position().top <= scrollPos && currElement.position().top + currElement.height() > scrollPos) {
               currSection = currElement.attr("id");

3. After expand/collapse/set all is triggered, all call back will be created that will scroll the page automatically to the section header that was last viewed.

if(typeof currSection !== 'undefined' && jQuery('#' + currSection).length ){
      scrollTarget = jQuery('#' + currSection).offset().top;
      if(typeof colomatoffset !== 'undefined'){
         scrollTarget = scrollTarget + colomatoffset
      jQuery('html, body').animate({scrollTop:scrollTarget});
   }, 700);


Scroll down a bit and then click the Expand All link placed in the header at the end of the menu. All ‘read more’ content should be expanded and then the page should scroll back to the section that was being viewed. The effect is more dramatic the further down the page is scrolled.

Section 1: Aaeton

Aaeton was a planet of the Aaeton system, in the Core Worlds region. During the Cold War between the Galactic Republic and the Sith Empire, an Imperial bioweapon activated on the planet. During the last days of the Republic, the government of Aaeton had authorization to allow its citizens to visit the generally off-limits neighboring world of Ragoon VI.

I’m from the planet Aaeton, only half-day’s journey from here. Young people from my planet often go on survival camping trips on Ragoon-6 when we reach fourteen years of age. We have a special allowance from the Senate because we gave the elders of Ragoon refuge when they handed the planet over to the Senate.

Section 2: Aaghra

Aaghra was the first planet from the star Zug in the Zug system of the galaxy’s Core Worlds region, not far from Coruscant,[1] the most politically important planet in galactic history.[2] It was a moonless world of molten rock.[1]

Aaghra was first mentioned briefly in part one of the Planet Hoppers article Aargau: For All Your Banking Needs, which was written by Cory J. Herndon and published on the Wizards.com website in 2003.[1]

Section 3: Aar

Aar was a planet[3] in the Aar system[1] of the Nijune sector,[2] part of the Outer Rim Territories.[1] It was homeworld to the Aar’aa species, reptilian sentients often employed as enforcers by the Hutts, a species known for its many crime lords.[3]

Aar was first mentioned in the 1997 novel The Paradise Snare, written by A. C. Crispin, and was also mentioned eleven years later in the 2008 The Complete Star Wars Encyclopedia.

Section 4: Aargau

Aargau (pronounced /är-‘gou/)[5] was a planet in the Zug system of the Core Worlds region, not far from Coruscant and the Corellian Run. It was run by and served as the headquarters for the Bank of Aargau, which was part of the InterGalactic Banking Clan. Numerous other banks and corporations were also based on Aargau, including the Z-Gomot Ternbuell Guppat Corporation. Aargau was an exceptionally wealthy world, due both to its status as a financial center, as well as the planet’s vast reserves of rare and precious metals.

Aargau was a member of the Galactic Republic from its discovery until the end of that galactic power. After the fall of the Galactic Empire, it was considered a New Republic stronghold. The region of space occupied by the planet would later fall under the hegemony of first the Galactic Federation of Free Alliances, and then subsequently Darth Krayt’s Galactic Empire. Despite this, Aargau took a neutral approach to politics, which meant that warring factions were mutually welcome to conduct business on the planet. The planetary government imposed only three laws on citizens and visitors, called the Three Statutes of Aargau. These laws focused on the export of Aargau’s natural resources, the absolute ban on weapons for visitors—and, conversely, the requirement to bear arms for Aargauuns—as well as maintaining the integrity of the Bank of Aargau. Breaking any of these rules was punishable by immediate execution.

Section 5: Aargonar

Aargonar was a dusty, desert-climate planet located in the Borderland Regions of the Mid Rim.

Aargonar was an insignificant desert world with few population.[2] The terrain was reminiscent of Tatooine for Jedi Knight Anakin Skywalker, with rock arches and stone spires dotting the once watery-planet.[3] The planet had several moons, including Aargonar 3.[2]

The planet was known to house numerous Sarlacc.[2] It was also home to Hrumphs and Gouka dragons.[3]

Collapse-O-Matic and Easy Footnotes Test

This is a test of how collapse-o-matic and easy footnotes can work togher. We have modified the Easy Footnotes[note]Easy Footnotes on the WordPress Plugin Repo at:  https://wordpress.org/plugins/easy-footnotes/[/note] plugin to allow for filtering before and after the footnote content. The modified plugin is available at Github [note]https://github.com/baden03/easy-footnotes [/note]

The filters used as follows:

add_filter( 'before_footnote', 'pre_footnote', 1);
function pre_footnote($footnote_content) {
	$footnote_content .= 'content to place before the footnotes';
	return $footnote_content;

add_filter( 'after_footnote', 'post_footnote', 1 );
function post_footnote($footnote_content) {
	$footnote_content .= 'content to place after the footnoes';
	return $footnote_content;

Print-Pro-Matic Placeholder Attribute

The placeholder attribute is used to add the print-me data to the page when print trigger and target will be added dynamically, for example: via AJAX or a Modal Window.

[print-me target="#print_me" placeholder="true"/]

This will not add the trigger to the page, just the targeting info for when the trigger is later displayed.

collapse-o-matic with inline link

This is an example of a collapse element with an inline link.

[expand title="this is a test with a <a href='https://plugins.twinpictures.de'>link</a>"]here is some hidden content[/expand]

the key is to use double quotes to wrap the title attribute and single quotes for the html inside the double quotes.

this is a test with a link

Collapse-Pro-Matic External Link with Find-Me Scrolling

This is a test Collapse-Pro-Matic’s ability to use external triggers to auto expand and scroll to other expands on the same page.
First we need quite a bit of text. Here is some from the Wiki entry for Star Wars:

Star Wars

Star Wars is an American epic space opera media franchise, centered on a film series created by George Lucas. It depicts the adventures of characters “a long time ago in a galaxy far, far away”.

The franchise began in 1977 with the release of the film Star Wars (later subtitled Episode IV: A New Hope in 1981[2][3]), which became a worldwide pop culture phenomenon. It was followed by the successful sequels The Empire Strikes Back (1980) and Return of the Jedi (1983); these three films constitute the original Star Wars trilogy. A prequel trilogy was released between 1999 and 2005, which received mixed reactions from both critics and fans. A sequel trilogy began in 2015 with the release of Star Wars: The Force Awakens and continued with the release of Star Wars: The Last Jedi (2017). The first eight films were nominated for Academy Awards (with wins going to the first two films released) and have been commercial successes, with a combined box office revenue of over US$8.5 billion,[4] making Star Wars the second highest-grossing film series.[5] Spin-off cinematic films include Rogue One (2016) and Solo: A Star Wars Story (2018).

Now we place a little expand element for R2D2 that we will reference below:

[expand title="R2D2" id="droid2d2"]...[/expand]
R2-D2 (/ˌɑːrtuːˈdiːtuː/), or Artoo-Detoo[citation needed], is a fictional robot character in the Star Wars franchise created by George Lucas. A small astromech droid, R2-D2 is a major character and appears in nine out of the ten Star Wars films to date. Throughout the course of the films, R2 is a friend to Padmé Amidala, Anakin Skywalker, Leia Organa, Luke Skywalker, and Obi-Wan Kenobi in various points in the saga.
English actor Kenny Baker played R2-D2 in all three original Star Wars films, and received billing credit for the character in the prequel trilogy, where Baker’s role was reduced, as R2-D2 was portrayed mainly by radio controlled props and CGI models. In the sequel trilogy, Baker was credited as consultant for The Force Awakens; however, Jimmy Vee also co-performed the character in some scenes. Vee later took over the role beginning in The Last Jedi.[1] R2-D2’s sounds and vocal effects were created by Ben Burtt. R2-D2 was designed in artwork by Ralph McQuarrie, co-developed by John Stears and built by Tony Dyson.

Now we have another expand element that includes in it’s content a link to R2D2 above using:

<a class="expandanchor" href="#droid2d2">R2-D2</a>
Astromech droid
An astromech droid is one of a series of “versatile utility robots generally used for the maintenance and repair of starships and related technology”. These small droids usually possess “a variety of tool-tipped appendages that are stowed in recessed compartments”. R2-D2 is an astromech droid introduced in 1977’s Star Wars and featured in all subsequent films.[14] The malfunctioning droid R5-D4 also makes a brief appearance in Star Wars.[15] U9-C4 is a timid droid sent on a mission with D-Squad, an all-droid special unit in Star Wars: The Clone Wars,[16] C1-10P is an oft-repaired, “outmoded” astromech who is one of the Star Wars Rebels regular characters,[17] and BB-8 is the astromech droid of X-wing fighter pilot Poe Dameron in The Force Awakens.

Here are two other examples of external triggers, one with and one without the expandachor class assigned, using the following code:

<a class="expandanchor" href="#droid2d2">test link one</a>
<a href="#droid2d2">test link one</a>
