Create and pass two Collections to Flow

Posted on by trevorseward

I'm attempting to pass two Collections to Flow on a button press. I'm collecting People (using the OOTB People screen) and Office 365 Groups. On the first screen, the user searches for one or more people, and on the second screen, the user selects one or more Groups on a List screen.

In the App.OnStart, I create the following Collection:

Collect(MyGroups, Office365Groups.ListOwnedGroupsV2().value)

I have two issues:

First is for the List screen -- how can I collect the Groups that have checkboxes next to their entry?

Second is, how do I pass both Collections (MyPeople and a new Collection based on selected Groups) to Flow? The idea here is to do a foreach on the new selected Groups collection and pass the MyPeople collection to each Group.

Hi @trevorseward

Not exactly sure what you scenario is, but it sounds like a ComboBox could be used to show and select the groups. The SelectedItems property should then give you what you need for the collection.
ClearCollect(colSelectedGroups,ComboBox1.SelectedItems)

You could send the collections to Flow using the new JSON function and then parse the data in Flow, ready for action.

Let me know if you don't come right.

Looking at a combobox, that isn't a good UI experience when many Groups need to be selected -- is there a way to collect the items the checkbox is associated with?

For example, how would I collect just Group 1 and Group 2 in this image:

After figuring the above out, it sounds like I would either create a new collection, or clear my existing MyGroups collection and using the JSON function (will have to look into that, too but thank you for mentioning it), pass the results to Flow for parsing.

This doesn't solve the Search/Sort question, but those are nice-to-have rather than required-to-have.

ComboBox is designed for large lists, as you can search directly in the ComboBox as well.

The check box isn't going to help much as this is not a mutli select control. You could add a gallery and as soon as someone clicks on the group, then collect that group to a collection. From the below it feels like this would be the best option here.

OK, that will work. But it doesn't answer how do I get two collections to Flow.
