Hello,
Following the last update of my site, all the Dataset with the filter “includes” in the Dataset of the site works badly, only the last valid element of the collection appears in the drop-down menu. although it was working fine before.
I tried to delete Datasets and dropdowns and creating them again but that doesn’t change anything. preview mode does not show me any runtime errors.
For the moment I had to remove several pages from my site because this one is unusable.
Like you already mentioned → it was working fine before?
And you did no changes? → Then someone else (Wix-side) did the changes and your code maybe broke down.
You are not the first one, who has difficulties/problems with DROP-DOWN.
The DropDowns have been upgraded. A new functionality was added on Wix-side.
