    In the showcase index page, theres tabs where the items are sorted by Alphabetical, recently updated, most popular, most recent etc....just wondering if its possible to have a tab there where items are instead sorted by a custom field? That would be awesome for myself.

    Not sure how much this would be of use to others, so if noone else is interested, i was wondering if i could perhaps get a lil help in adding that(or using an existing tab item to sort by the custom field).

    The canonical custom field data (stored in its own tables) is not joined to the item during the fetch process, so sorting (which is part of the fetch process) isn't possible.

    Just so you know.... Custom Fields data is also CACHED for each given item and that cache is stored serialized in a blob field in the item record (and therefor is not something that can be sortable via SQL). After the item(s) have been fetched, they are prepared and part of that process is unserializing and preparing the custom field data for display.

    With that said, I DO have SOME (not all) of the code you'd need already in the Item Model that lets you fetch items BY custom field(s). This is used exclusively by the searching for items by custom field functionality. This would still have to be further tweaked as it doesn't handle SORTING. The more I think of it while typing this, you'd probably have to write your own completely separate fetching method as the sorting method in the item model being used won't work for custom fields.

    This isn't something that I'd add to core, but am willing to add code to the model(s) if needed to help with peoples custom development towards stuff like this.

    Late to the party, but definitely would like sorting by custom fields. One use of the Showcase I see is for showing lists of football players sorted by position.

    This is not possible. The latest version of Showcase 2.x does have Filtering by custom fields however.
