As requested here this add-on collapses quotes over a specified limit, and adds a "read more" link to expand the quote.
This add on makes use of a jQuery plugin called jQuery Expander Plugin by Karl Swedberg.
This add on also requires the quite brilliant Template Modification System.
If you do not have the Template Modification System, you can follow these instructions. (Not recommended)
Here's a collapsed quote in the default style:
Here's a collapsed quote in the new "bottom centre" style:
And an expanded quote:
There are numerous customisations available through the Admin CP > Options > Quote Collapse Options.
You can change the "slice point" to control how much of a quote is shown before it is collapsed, the Expand/Collapse text and the animation speed at which the quote expands or collapses.
You can control the look of the Expand/Collapse text in the QuoteCollapse.css template.
1) First ensure you have the Template Modification System installed.
2) Download the add on and upload the contents of the "upload" folder to your root path.
3) Configure your options (optional).
