Hi Tuan,
I had already made these bug report when eDocman 1.5.5 came out, but now it is 1.7.0 and they still have not been patched.
So every time I update eDocman, I have to manually correct these two files.
/components/com_edocman/assets/css/style.css
/components/com_edocman/view/common/documents_default.php
I have made a super detailed document explaining those two bugs and how to solve them.
Please see attachment.
And thank you for correcting this for next release
