How to animate page loading

Content

Hello Experts,

We have below requirement.

a. How can we have dynamic dropdown in VBCS? Combobox or SelectOne component fetches its data before rendering the component. Rather we want a behaviour where user will start typing and with delay we will get data for the typed text from the Fusion system and populate in the options of the combobox and Selectone.

b. We have page A. On click of button in Page A we want to navigate to Page B in animated fashion. Slow loading or Page B or loading of Page B from either right/bottom side of page. Can we achieve this animated loading of the page?
