This stumped me at first. There are two ways to do this.
1)Albums containing galleries – The albums do not show in the site, just the galleries. There can only be one album per row. If there are 3 galleries in the album, your row will display the 3 galleries left to right. If your album has only one gallery, only one gallery will be displayed on the row.
2) Albums containing albums – You can create an album and put other albums in it. If an album has 3 albums in it, the 3 albums will display left to right in the row. When an album is selected in your site, then the galleries will display the same way in option 1.
This is hard to explain, so I hope this helps.
