There is this very good Adalo tutorial on how to filter a list in your app \> [How to make a list your users can filter - YouTube](https://www.youtube.com/watch?v=dflwpniED-s)

That works fine as long as Categories & Movies are related such that:  
A Category can have multiple Movies & A Movie belongs to one Category

But how could I set this up when  
A Movie can have multiple Categories & A Category can have multiple Movies?

In this latter case the option to set a Custom Filter on the list of ‘Current Movie \> Categories\> Name’ isn’t available

Thanks for the welcome… as you can probably see I’m going up a learning curve, lol.

Many thanks for the solution, that seems to do what I want. I’ll test a bit further when my internet connection is better!

OK, just managed to test a little further…

The only issue I see is that with nothing selected in the drop-down (ie it says Select…) with the one to many relationship I see all movies in the list (as I’d want) but with the many to many relationship I see none.

What I’d really want is to see all movies showing if no selection is made, if that makes sense.

Thanks!

You can add another list and add a visibility condition for that list Other Components\> Category( drop down name )\> Name\> is equal to\> empty.

Like this.

Thank you
