Filter a Gallery based on a values belonging to a collection

[Anonymous]

Hello,

I have a Gallery I want to filter. I want to display all elements whose categoryID are in a list of values, defined as a collection.

My collection "Categories" is : 1,2,3,4,5

I tried something like : Filter(Gallery, categoryID in Categories) but it doesn't work .

All the examples I could find with "in" operator only work with one value, not with a list (eg: "1" in categoryID)

Can anyone help on this, this would be so bad not to be able to do this !!

Regards

Guillaume

Hi @Anonymous,

Would you please share a screenshot of the formula that you used to create the "Categories" collection?

Any error messages showing out with the formula you used?

I just tried that formula from my side, and it works.

The formula I used to create the collection is as below:

Collect(Categories,["1234","235","346"])

In addition, you may also take a try with the formula below:

Filter(Gallery, categoryID in Categories.value)

Hello Michael,

thanks for the reply. I used your way to define the following collection : Collect(SelectedCategories; ["1";"2";"3";"4";"5";"6";"7";"8"])

But sill I have the following error (translation from French) : Suggestion, a part of the formula can't be evaluated from distance. The right side of the operator "in" is not a column name

Hi @Anonymous

You need to add the column name, probably.  Please try this:

Filter(ServiceCatalogue, CategoryID in SelectedCategories.Value)

Also, you have an extra ; at the end of the formula

Hi @Anonymous

Form your picture it seems you have an extra ; at the end which is causing the error. Try to remove it and see if it works

Hello @Meneghino,

thanks for spotting this, now I remember I'd already tried this (with "Value"). Doesn't work either :

Did you find any solution? I'm stuck with a similar problem

Hi @Riccardo_A,

It sounds like you are having an issue filtering your gallery against another collection. 

Can you share what formula you are currently using and how your app works? Screenshots would be helpful.
