Display selected scene thumbnails only (vtour droplet)

I know there's a similar thread for this http://www.krpano.com/forum/wbb/inde…44582#post44582
but I really can't make it work. I have 2 room types in my vtour and total scenes are around 10. I only want 1 thumbnail for each room (total 2)
My temporary solution for now is I emptied the thumburl of the scenes that I don't want to show thumbnails
<scene name="scene_Single_Room_2" title="Single Room" onstart="" thumburl="" lat="" lng="" heading=""> It works immediately (see attachments)
But what it did is it only made the rest of the thumbnails invisible, there's still a gap between which are the allocated thumbs for the other scenes.
I really need this solution urgently. Can anyone help how to remove the gap?

Thank you so much Umalo, it's working now.
for others just follow Umalo's thread on doing this. Go here
