np @nacmartin but keep in mind that i didnt apply any change for placeholder. i have to learn a bit more about redux form and how using template for liform react as i dont want tu use bootstrap as default form template ^^. i'll try to make PR as often as i can, thanks again for your great bundles 👍

I understand. The issue is that we have our theme for very specific widgets, which was the reason behind this. We don't use the full specification (I don't think we need for instance dates), but we have widgets that are tables with turns for workers, or choices displayed as big buttons with icons (season winter/spring/summer/autumn with their icons) and things like that. So in short, it is not a general purpose theme.

So we provide a theme based on bootstrap instead and there is the possibility of extending it.

There is a theme based on Material UI written by another user, for instance, also supporting a subset of the widgets afaik https://github.com/samuelbriole/react-liform-material-ui-theme
