Hello.
1) login as user who already created few albums in group
2) navigate to group's album. for example
3) look at sidebar. You will see lists of "My albums in group" and "Other albums". Each list has it's own "Show more button link"
4) Press on any "Show more" under "Other albums" for example.
Result 1: list "Other albums" will be "opened" and display more item.
Result 2: list "My albums in group" will be "opened" too (but it should not).
Thanks.
