Multiple choice collection

[Wowwowha]

If I have a Drop Box that allows multiple selections, Is it possible to record the multiple selections into a collection?

Assuming your control is a ComboBox control, this can be done by copying the following formula to ComboBox.OnChange:

ClearCollect(sel, ComboBox1.SelectedItems)

This will create a collection "sel" which will always contain the selected items.

Hi @Wowwowha,

Could you please share a bit more about the Drop Box that you mentioned? Is it a Combo box control?

If the Drop Box that you mentioned is a Combo box control,  I agree with @dinusc's thought almost. I have made a test on my side, please take a try with the following workaround:

Set the Items property of the Combo box control to following formula:

Choices('20180825_case1'.Status)

Note: The '20180825_case1' represents the SP list data source within my app.

Set the OnChange property of the Combo box control to following formula:

ClearCollect(Collection1,ComboBox1.SelectedItems)

or

Clear(Collection1);ForAll(ComboBox1.SelectedItems,Collect(Collection1,Value))
