IAMDORIAN  CORRECTION:

Not a Will Robinson episode . . . seems the Theme developer fell behind in updating his Theme. Looks like Accordion is working fine.

Developer is quick to respond and knowledgeable. Many thinks.  
(Version 1.5.1)

IAMDORIAN  DANGER WILL ROBINSON! DANGER WILL ROBINSON! DANGER WILL ROBINSON!

This version broke the tabs closed until opened function, and even the click to close function! What up wid' dat?? Went too find an older version to uninstall v1.5.1 and no luck. Arrrrrgh!

DANGER WILL ROBINSON! DANGER WILL ROBINSON! DANGER WILL ROBINSON!

Hope they nip this one in the bud, toot suite!  
(Version 1.5.1)

DENNY DOUBLEPLUS MARKETING  I just updated my Accordion to this latest version - 1.5. It's nice to see the auto-update feature now included, plus having everything contained beautifully in the Page Inspector. All of the plugins options are smartly laid out and quickly accessible. This and all of the other amazing plugins by this hard-working developer are simply a MUST-HAVE for RapidWeaver owners - infinite options for building webpages.   
(Version 1.5)

PXL  Though this is nice looking plugin for Rapidweaver, it's very unstable. It's loves to stick.  
(Version 1.1.3)

RADDLE  Another very, very cool plug-in from an inspired and responsive developer. Excellent!  
(Version 1.0b7)

ANTHONY SIGALAS  Another excellent plugin for Rapidweaver from YourHead. Accordion is a very useful plugin and I use it in many of my webpages. However it is still in late beta mode (current version 1.0b5), so approach with caution.

I have bought all the plugins from YourHead and this one is certainly one of the best. It makes for a less cluttered page, using a vertical tab technique via lightweight Javascript. You have to see it, to appreciate how cool it is.
