Additionally, it might be fun to code than visually confirm it works, we were actually able to develop faster by writing this feature in unit tests first.

04/28/2022, 1:59 AMThanks i did exactly that. It was little difficult to actually figure out that i need to use transformation. Just one question - is it possible to delete the entire names that are spans on back press in soft keyboard rather than a character at a time.

05/04/2022, 1:32 PMWrite unit tests to test the interface. In my base I was looking for {{userid-xxx}}. If it detected that the last } got deleted then I'd return the entire backing string before the first {

05/08/2022, 11:18 AMIn my case i have range start and end which is use to style replaced text on drop down selection. But when user deletes the range is out of bound. Eg. @abc is colored 4 chars. Range is from 0-3. So delete c my range is till 0-3. So basically beed to delete the span from span list of this happens. I think having some of delimeter to figure out start and end of span should help.
