I´m new on PEGA, I´m completing right now the UI Specialist Course, and i have one doubt: when designing a harness/section, is there any limit in the number of fields you can drag in? In addition , regardless there is a limit or not, does the number of fields in a harness affect the compliance score?
Pega follows same UI standards as defined by W3C. The benefit you get with PRPC is, you can create your UI without knowledge of any front end technology, even HTML knowledge is also not required.
When it comes to limiting the number of fields, you should follow user readability standards. When ever your fields are more, you can divide and group them in logical way. Pega doesn't limit for any number of fields, you can add as many you like.
Absolutely not, though obviously it's trade-off between performance and user experience. Long and messy UI isn't helpful for end-user. Pega discourages to have excessive fields in UI. And suggests to break down the UI in multiple components as collapsible/tabbed layouts etc. Pega also suggests screen-flow to break the long contented UI.
Hope it clarifies your query, kindly notify by marking this post as answered.
