Frequently Asked Questions
Common questions about Collapsing Categories
If you want to use images, you can upload your own images to http://yourblogaddress/wp-content/plugins/collapsing-categories/img/collapse.gif and expand.gif There is an option for this. I have selected a category to expand by default, but it doesn't seem to work If you select a sub-category to expand by default, but not the parent category, you will not see the sub-category expanded until you expand the parent category. You probably want to add both the parent and the sub-category into the expand by default list. I can't get including or excluding to work Make sure you specify category names, not ids. There seems to be a newline between the collapsing/expanding symbol and the category name. How do I fix this? = If your theme has some css that says something like sidebar li a {display:block} that is the problem. You probably want to add a float:left to the .sym class No categories are showing up! What's wrong?"
categories. Please check the options in the settings page (or in the widget if you are using the widget)
As of version 2.0, there are several default styles that come with collapsing-categories. You can choose from these in the widget settings , or you
modify it slightly to your needs. The following classes are used: * collapsing-categories - applied to all ul and li elements * list - applied to the top-level ul * item - applied to each li which has no sub-elements * expand - applied to a category which can be expanded (is currently collapsed) * collapse - applied to a category which can be collapsed (is currently expanded) * sym - class for the expanding / collapsing symbol An example: <ul id='widget-collapscat-15-top ' class='collapsing-categories list'> <li class='collapsing-categories post'><a href='http://mysite.com/your-website/about-your-own-site/' title='About your own site'>About your own site</a> </li> <li class='collapsing-categories'><span class='collapsing-categories expand' onclick='expandCollapse(event, "▶","▼", 1, "collapsing categories"); return false'><span class='sym'>▶</span>Web hosting</span> <ul id='collapsCat-176-15' style="display:none"> <li class='collapsing-categories post'><a href='http://mysite.com/your-website/web-hosting/about-webhosting/' title='About webhosting'>About webhosting</a> </li> <li class='collapsing-categories post'><a href='http://mysite.com/products/webhosting-1/' title='Webhosting #1'>Webhosting #1</a> </li> <li class='collapsing-categories post'><a href='http://mysite.com/products/webhosting-2/' title='Webhosting #2'>Webhosting #2</a> </li> </ul> </li> <!-- ending subcategory -->
