K2 tag and user lists and modules in sidebar?

Hi,

I have a list of K2 items, obtained by filtering

a) by author
example:
http://www.lomyatezba.cz/2013/2013-01/i ... nkov%C3%A1)

b) or by tag
example:
http://www.lomyatezba.cz/component/k2/i ... ag/HITACHI

How I assign to this views modules in sidebar?

Hi,
it wont be easy, because normally those information are connected with component /current showed item/.
So the best solution would be write or find module which have those features.
You can try to use / modify module "K2 tools"

(1) Select module functionality [Authors List]
(2) Configure Authors List Settings
(3) Change code of module to show only one selected author

p.s.
For second question:
I was thinking about use to 2 solutions: DM K2 XML Exporter /or generate RSS from your URL/ and module which import & show those XML.

Or use: http://extensions.joomla.org/extensions ... ions/13890

I have found also this module: DM K2 Related Articles - allows you to display K2 "related articles" in a module; the module will display related items (by tag, by author or category) when the user is reading an article. So you should try it or contact with developer to be sure.

I hope this tips will help you
