What kind of functionality does your website provide? I ask because thunkable can replicate many but not all things a website completes. Maybe provide a link to your site?
You may be able to use Framwork7 within the webViewer, but that kinda defeats the purpose of using thunkable in the first place IMO. Nonetheless, it’s a super cool potential feature that I have seen users like @actech discuss. I would love to see a nice working version (maybe i missed this part in the examples)
If it is a simple contact form and info about your company, this is very easy to accomplish. You could potentially add a chat feature like a ‘help desk’, a harder task but very useful if you don’t have regular face-to-face contact with your users.
