Create a text frame. Select the frame with the Selection (black arrow) tool, and choose Object > Text Frame Options. On the General tab, set the Columns to Fixed Number, and choose 2. Set the Gutter to be the space between the two columns.
Enter the text in the left column, and at the end choose Type > Insert Break Character > Column Break. Then enter the text for the second column.
That is really cool thanks a lot!
How do I make sure any text meant to be below the text frame (that is part of the main document flow) doesn't collapse underneath it?
In addition, is it possible to have different widths for each of the columns?
We can give you better answer if we know what kind of data contains the two columns?
If your two columns contain for example the following types of data:
Address: Fifth Avenue 23
Tel .: 123456
In this case you have a single column and use tabs.
(or you can create a table with 2 columns...)
however, as I said before, we could give you better answer if you had described exactly your problem at the beginning
