How to set a component not subject scrolling

Good morning guys,
I wanted to ask you a question that I have been keeping for several months thinking that I would be able to find the solution on my own.
How is it possible to block a component not making it subject to the action of scrolling the page, to understand, like the bottom navigation bar of Instagram.
I have seen that in many Apps in the Backendless Viewer there are the blocked components I am talking about (ex. InstaClone), so I suppose it is possible to set them, but how?

Thanks in advance,
Marco

Hello @Marco_D_Alessandria

You could set property Position to fixed, and Bottom(Position tab) to zero at UI Builder style settings.
