Hello,
I am sorry but I not found on yours site any link to Media Library, with that me very difficult check all what you said.
1) How I can have in the frontend the button to order the media in a category by title ascending/descending or Author?
That exist in Pro or Shop versions. You can see features at link:
ordasoft.com/MediaLibrary-Documentation/...ture-comparison.html
In free version will need add that functional
2) I would hide the buy-it button, because I use your component just to manage a library of a flyfishing club.
In Pro/shop version - ypu can hide that through backend options. In free you may self check code frontend and hide that.
Please check file "medialibrary.html.php"
In free version will need add that functional
3) In a title of a category or sub-category I wouldn't see the name of the category or sub-category repeated twice.
How i can check that?
4-very important) Could it be possible to have the navigation buttons to go from a sub-category to the previous category or to cameback to the main category?
Now at time menu creation - you can set show "Back button" to that component or no! Please check options at right top corner for MediaLibrary Menu
Also you have in Joomla Module "Breadcrumb". Please turn on - it if it turnoff. Media Library support that module. That module simplify navigation through Media library
Thanks,
OrdaSoft team
