Has anybody had the chance to try out these repeatable fields yet?
I have one more update that I put in the latest commit, though this applies to all fields, not just repeatable fields. This update enables you to create columns rather than just rows. You can now specify a width percent in any field's input settings (or use the columnWidth property on an inputfield from the API). Here's a screenshot of the new setting:
And here's the result (combined with a repeatable field). In the screenshot below, I've set building_name to have a width of 50%, floors to have a width of 25% and height to have a width of 25%:
Note that because this involves some stylesheet tweaks, this may not work on 3rd party admin themes right away. But I'll be happy to assist admin theme developers to add the necessary stylesheet tweaks to make this work.
