Filter without duplicates - External Collection

Hi guys!

How are you? Hope all of you find well.
First of all, sorry for my english (I´m a Spanish speaker).

I´m using Sheetdb for an external collection. One of the columns (Cities) are using like a filter.
The thing is each city appears for each event so here is the problem. The cities are duplicates:

There are any way to exclude duplicates but when select the city in the filter appears all the events of the city selected?

Thanks in advance!

You could have a cities collection, which does not have duplicates, like a list of ‘city options’. This could be inside Adalo. Just a collection with one property ‘city name’. Then manually populate this list yourself without duplicates.

Then, assuming you’re trying to filter a list, have city name = dropdown city name. As long as the text matches of course.

Thanks a lot @theadaloguy!

You mean: If the city name are the same in the Adalo collection and in the External collection the results of the list will match?

Thanks again.

Yeah exactly, just matching the text from your options list to a field in your main database

Hi @theadaloguy!

Hope you find well.

Sorry for my late reply.
I have solved the problem creating an other external collection only with the “city name”. Without duplicates.

When I select the “city name” in the dropdown all the events matching appears.
Thanks for your help and ideas!
