Frequently Asked Questions

Common questions about Side Matter

As of version 1.4, the Side Matter options menu has its own settings page. It can be accessed from the Side Matter link under the Appearance menu on your admin screen. My notes don't appear. Many themes are one-column by design and do not include a sidebar. Without a sidebar, Side Matter has no place to put your notes. Make sure that your theme includes a sidebar and that you've placed the Side Matter widget within that sidebar. My notes just sit at the top of the sidebar. This usually happens because of a conflict with your theme or another plugin. Caching/minification plugins are a common culprit; try adding /wp-content/side-matter/js/side-matter.js to your caching plugin's exclusion list if it's interfering with sidenote display. Theme conflicts can be difficult to pin down, but are most often caused by some idiosyncratic bit of theme CSS or JS. (For example, the theme Twenty Eleven can be made to work with Side Matter by adding a few lines of CSS.)
Not all themes are built to incorporate a plugin like Side Matter. It works well with most base themes that include a sidebar, but it isn't guaranteed to display notes perfectly under all themes. A little tinkering with note offset or CSS will fix most problems; in other cases, consult your theme's developer. My notes appear at a vertical offset. Some themes mysteriously cause sidenotes to appear at an offset from their corresponding references in the text. As a workaround for this problem, Side Matter's options menu includes a field for arbitrarily adjusting your notes' vertical offset.
Yes. Use the custom action side_matter_list_notes in your sidebar template, as seen below: <?php
?>
