Combo Box Confusion

I have a Combobox. The Items Property of the Combobox is as follows:

Filter('Teams', drpEventType.Selected.'Name (Title)' in 'Event Type'.Value )

This works well, it filters the data from the Teams list based on the selection in another dropdown. The user can select from the available Teams. Were it breaks is when I set IsSearchable to true. I enter a search string and nothing happens. No items are found/displayed for seletion. I set the SearchFields property to the same property that the dropdown is displaying, in this case ["Title"]. Is there something else I need to do? Am I doing something wrong?

Thanks.

Is your 'Event Type' Column a multi-select column? I assume so as the search (with a filter like that) will not work properly.

Yes it is. I have resorted to creating a collection in the OnChange for the Event Type dropdown and setting the Items property of the Teams drop down to the collection.

The only thing I need to do now is clear the selection from the Combo Box when the event type changes. That isn't as simple as I thought it would be. But making progress. Is this the best solution, or is there a way to get it to work without the collection?

Thanks.

You don't need collections or Change actions for this. It will work with the correct formula. But you really need to do it from the Dropdown.

What is the Items property of drpEventType?

Items = 'Event Types'. It is just the list name.

Here is what I would do:

1) Change the Items property of the drpEventTypes to the following:

AddColumns( 'Event Types', "recs", Filter('Teams', 'Name (Title)' in 'Event Type'.Value ) )

2) Change the Items property of your ComboBox to drpEventTypes.Selected.recs

3) To force a reset of any "search" text entered. Set the OnChange action of the drpEventTypes to : Reset(yourCombobox)

That should give you the functionality you want.

That solution did not work. The column was added to the Event Types drop down but it was empty. Is that Filter correct? The In the Teams table, the Event Type column is a Multi select Lookup Column.

The solution works well, so there must be an issue with the filter as you suggest.

My assumption was that you had a Multi-Select Choice column in your List. You are now stating that it is actually a LookUp column?

Please verify.

Yes. The Event Type column in the Teams list is a Multi valued Lookup column. The lookup list is the Event Types list.

Yes, to verify I just gave it a test - all works fine with this formula:

AddColumns( 'Event Types', "recs", Filter(Teams, 'Name (Title)' in 'Event Type'.Value ) )

So, let's review.

1) In the Teams list, you have a Lookup column that is Multi-Select and is a Lookup to the Event Types list?

2) In the SharePoint definition of that column, you are using the Value to connect as 'Name (Title)'?
