hey liquid squelch! i think you can do that using the HungryFEED custom templates which are a new feature in combination with some clever CSS.
In HungryFEED settings edit custom template 1 to look something like this:
<div style=”width: 33px; float: left;”>
…. (your HTML here) …
</div>
then within your post, you would need to surround your HungryFEED shortcode with a fixed-width wrapper like so:
<div style=”width: 100px; float: left;>
[HungryFEED url=”…” template=”1″]
</div>
so what this will do because each item is floated to the left with fixed width of 33 pixels, and they are contained within a 100 pixel div, then they will appear horizontally and it will line wrap at 3 items. of course you can adjust the pixel width based on your needs)
i don’t know what your feed looks like and there may be some tweaks necessary based on your wordpress theme, but it technically should work.
