Hello,
currently i use the accordion menu provided by the asp.net toolkit.
The problem is that it is not Seo friendly. So what i am looking for is an accordion menu with the following characteristics.
1) Seo friendliness
2) Preserving of the selected index, on post-backs.
3) Small in k bytes
4) Free of charge
Do you have anything in mind?
(1) Asp.Net Accordion is obviously SEO friendly but it lot's more depends on how you use it, I generally use BulletedList inside the accordion panes to dynamically bind the related links.
and they work great for me, they are user friendly(If designed properly), and also SEO friendly as well.
(2) This post on asp.net forums can help you answer your postback related problems.
(3) this is not too good but not too bad (I think)
(4) this is free and even open source you can use/change source code
So if you want another option only because of SEO Friendliness, then don't do that, another option is jQuery UI accordion
