Thanks for providing detail around what you're looking for, Doug! That helps me respond with more confidence: sounds like the React Form component that is part of Kendo UI will save you time and trouble. I'm part of the KendoReact team (the team that's building the React-specific UI library within Kendo UI), and one thing we've discovered is that writing a Form component may look simple, but is far from trivial to write - and to get right. To help developers with this, beyond the Form component itself, we created design guidelines for writing great forms in React (linked with this response) - a reference document that combines years of experience and in-depth research. My best advice is to try the KendoReact Form (and any other components your app needs) in a PoC and test it in action. The library is well documented and if you sign up for a trial, you also get free technical support from the team - we've done our best to make evaluating (and using!) our product as easy as possible.

Why go for a paid solution, when battle-tested Bootstrap is free? Bootstrap is easy to configure and customize, and is the most popular frontend library. Especially if this is going to be an in-house solution, I'd go for Bootstrap. Unless there are specific features you need that are only available in Kendo UI.

Hello. I understand you already made your decision about React. I would like to share my experience with you. We're sucessfully working with Angular and Devextreme. After about four years, I can confirm that DX is a mature and very complete line of components and is growing and improving at each major release. I would not go back in my decision (please note that we're using React too, but IMO, Angular is better and more productive when it comes to LOB / Line Of Business solutions).

Of course, IMO, it's also just a little bit expensive if compared with other products.

React on Devextreme came a little later and some components are still under development (as far as I know) or, to be honest, it depends on which DX library you will use (there are two libraries: DevExtreme Reactive and DevExtreme React UI) .

Kind Regards.
