Text frame Colums

Hey there, I'm trying to add some text at the end of a score. I'm using a text frame, I tried to make a second column to use the full width of the page.
I found some solutions working in the old versions, but those do not work anymore.
I also tried to add other frames laterally, as if they behaved like text boxes, but I wasn't able to have them side by side.
The tabulations key inserts something like a space, so i can't use it as a work around.

Is there a way to force it to add some columns in a text, or to add several text boxes side by side?
