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:

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>

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:

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;
}

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

Demonstration:

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.

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]

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]

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.

Section 5: Aargonar

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

This is a test of how collapse-o-matic and easy footnotes can work togher. We have modified the Easy Footnotes¹ plugin to allow for filtering before and after the footnote content. The modified plugin is available at Github ²

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;
}
