Subpage as Expandible Text Shortcode Plugin

Intended users: editors, authors, contributors

This plugin will allow you to display the content of subpages as expandable links.

Simply add [subpages_expand] to any parent page. The titles of each of the subpages will be displayed there as clickable links. When the user clicks the link, it will expand, displaying the content of that child page.

Clicking the title again will collapse the content.

If you have a single file (ending in “.zip”), then use the Upload method. If you have multiple files, use the Files method. If you’re installing from WordPress directly, just hit the big ‘Install Plugin’ button.

Upload

1. From the plugins, add new screen, choose upload
2. Navigate to where the .zip file is located and select it
3. Make sure to activate the plugin once it is installed

Files

1. Upload the entire directory (not just the files) to the /wp-content/plugins/ directory
2. Activate the plugin through the ‘Plugins’ menu in WordPress

Q. Does this work on posts?

A. No, only on pages

Q. I added the shortcode and nothing happened!

A1. Make sure you spelled it correctly

A2. Make sure you added the shortcode to a page, not a post.

A3. Make sure your page has sub-pages.

A4. Verify that your parent page and all child pages are published (not draft or pending)

Q. My page has more than one subpage, but only one is showing up! When I click the link the other subpages are in the text that appears.

A. You have an HTML error in one of your pages. If you have mismatched div tags, the child pages after that can get “trapped” in the first child’s content.

Q. Error 324 (net::ERR_EMPTY_RESPONSE)

A. This error usually occurs when you try to have this shortcode on a child page.
You cannot nest this shortcode (i.e., have it on a parent page and one of the child pages).

Q. It takes a long time for the page to display.

A. The time it takes for the page to display is the time it takes for all of the subpages’ content to
load. If you have subpages with lots of content (or javascript that loads in content), it will take time for
WordPress to load that page.
