Unfortunately you can’t do this automatically unless you use the css3 column module which isn’t widely supported yet. You’ll just have to split the list as appropriate and float them in columns.
Its a client requirement. I am developing one page for newspaper section. I done two column using float attribute and to demonstration the client but he doesnt want to that tricks. They need automatically to stretch the content in second column. If you have any other ideas using javascript then please share me that ideas.
I hope you saw the newspaper daily. In that newspaper the paragraph is not enough the space in the first column to stretch the rest of the paragraph in second column automatically. I hope you understand.
