How do you make the date viewer go behind other elements on my screen?

Right now I’m working on a project where the user has to select a date, and as part of a work around with the date picker always having the default as today, I created another label on top of i that when clicked, called the date picker.
I want this label to be on top of the label of the date viewer because the date viewer one doesn’t let me show the date I give it.
This label is also higher up in the ‘hierarchy’ of elements, so it should be in front but it isn’t.
Just a heads up but, I can’t show you the code as I accidently deleted it and am trying to reconstruct it. I can give you pictures of the design if that would be helpful.
Thanks to anyone who can help, and if you need any clarification in what I mean just ask.
