    Hi,

    Yes, we can set the limit of items that a user can select in a combo box.

    Add the below Fx formula on the OnChange property of the Combo box.

    If(CountRows(ComboBox1.SelectedItems)>1,Notify("you can not select more than 1 item",NotificationType.Error) & Reset(ComboBox1))

    In the above example if user will select more than one item he will get an error notification, but it will remove all the previously selected items from combo box.

    Hope this helps.
     
    Thanks!

    Hi ccqn 
    If you put this OnChange of the Combo Box (example for a maximum of 3) 
    If(
   CountRows(Self.SelectedItems) = 3,
   Notify("Maximum selections reached", NotificationType.Information),
   CountRows(Self.SelectedItems) > 3,
   Notify("Maximum selections exceeded", NotificationType.Error);
   Reset(Self)
)
    it will provide a notice if the maximum, and clear the box if this is exceeded. There is no way of only clearing the last item.
