Displaying multiple values in an Item Pane Column

Awasu's Item Pane can display data about the feed items you are displaying in a Channel Summary Template in a sortable column format. You can specify Item Pane columns globally that affect the display of all Channels or you can specify Item Pane columns on a Channel-by-Channel basis.

If you need to display multiple values in single Item Pane column you can do so by specifying a tiny {%REPEAT%} ... {%/REPEAT%} loop in the Item Pane dialog box.

Examples

Categories

To display multiple Category values in a single Item Pane column delimited by commas:

{%REPEAT% category insert=, }{%ITEM-METADATA% category}{%/REPEAT%}
Name the Item Pane column something like "Categories" (notice that's plural).

Authors

Similarly, to display multiple Author values in a single Item Pane column delimited by commas:

{%REPEAT% author insert=, }{%ITEM-METADATA% author}{%/REPEAT%}
Name the Item Pane column something like "Authors".

The finished product

Here's what the item pane looks like displaying multiple Categories.

Admittedly, there is kind of an extreme example here, as the blog author had written a 'Most popular posts' blog post and attached 11 categories to that single blog post.
