Hello!
I finally reached the point where I could use Data Binds, but still have questions after reading up a bit.
For a Form and each Component within it, how do each of their self.item[’ …’] relate to one another. Consider, for example, the tag attribute, which is available for a Form and virtually all Components within it …
If, say, for MyForm as well as for a Card component, a Drop-Down component, and a Nav-Link component within said MyForm, I Data-Bind their tag to self.item[‘foo’] – that is, to the identical dict() key string for each – how are each distinguished from one another? Does each have it’s own self.item[’…’]?
Understanding this will help me understand the data-structure and scope of self.item[…] (or for each self.item[…] if there are multiple in my contrived example) – crucially, so that I don’t clobber data. 
Thank you in advance!
