All,

The lightbox popup to select a k2 item only shows a search field on Joomla 3:

On Joomla 2.5 it used to be much more complete with dropdowns for categories and language.
I have a site with hundreds of items in 4 different languages, it is impossible to find the articel you need without these dropdows.

Does anyone know of a workaround or a way to add these filters in the popup lightbox ?

Can you provide some context?
Is this the modal from the menu item?

Yes, that is the one.
I also use k2XT link Item, it has the same modal and thus the same problem.

If the colums would also show category/language then that would also be a good workaround...

Ronny, this is a valid feature request.
Can you post this here -> github.com/getk2/k2/issues so we can evaluate it?

Thank you for your feedback :)
