When outputting lists it is often helpful to display the list items in multiple columns. This allows more items to fit on a single row, thus taking fewer rows to display the list. The example code in this article allows for an arbitrary number of columns to be rendered for a given list. The number of columns can either be hard-coded or passed in to the transform as a parameter. For this example we will hard-code the number into a variable.
There are a minimum of four techniques you can use to render your list items in multiple columns. This article covers displaying items top-down left-to-right with items combined in a single table cell per column. Links to three other articles, demonstrating different techniques, can be found in the See Also box.
Create the Items.xml file
We need a simple XML file to transform that contains our list of items that we can output in multiple columns. Copy the contents of Listing 1 into a text editor, and then save the file as Items.xml.
Create the Columns-Vertical-Combined.xsl file
Now we need a transform to output our list items in an arbitrary number of columns. You will find the number of columns hard-coded to seven in the COLS variable. Feel free to adjust this number to whatever you choose; or, if you prefer, you can change it into a parameter, and then pass in the value when applying the transform.
Copy the contents of Listing 2 into a text editor, and then save the file as Columns-Vertical-Combined.xsl. Be sure to save it in the same folder as the Items.xml file.
