Float - Absolute position message

Hi.
Sorry, I don't know if this is the correct channel.

I'm trying to create some custom message viewer, with a mapview.

When user 'press' the map, it need to convert the view into a 'position: absolute'.

When trying to add the position absolute, it goes relative to the message/bubble not the 'chat view or like I want the entire screen'.

Someone already done something like this?
