Hi!
Thanks for your reply but I did not see any notification in my inbox.
Here is the demo I'm talking about. It is in the documentation

I would like to present the hotels just like it is in the gallery above or in the attached file, Then list the hotels below the gallery .
I tried to use {loadmodule simple_gallery} in an article and it failed.
Is there anyway to use the simple gallery in an article? if yes, how?
How could one list the hotels on a page like in check availability ?

Hello vietvh!
Thanks for the quick reply!
If I understand well, one has to subscribe before really using the component and it will work?
