Formatting

You might try using the highlander-grouping so that only one item at a time can be expanded. This is explained with examples in the collapse-o-matic documentation.

If you want the ability to expand/collapse multiple items, and maintain a fixed layout, you will need to do this with CSS. This is beyond the scope of our plugin support, but if you need technical assistance in this matter, we would be happy to assist you as part of the personal support that comes with Collapse-Pro-Matic.
