Below I put an email input that I use in SharePoint and it's very inefficient to have to search for the names the way it currently does. Lets say I have used this name before and I want it to show up a dialog box below to click for easy use. Kind of like Outlook Emails work....is this possible?
Sounds like you'll need something that's not out of the box.
Here's a breakdown of what I believe is needed:
- a place to store/access the last used emails for the autocomplete to use(sharepoint list,sharepoint view, browser localstorage, 3rd party db, etc)
There is other ways of getting this, a custom built wsp etc. but I favor CSOM since that's the direction sharepoint customizations appear to be going in order to maintain compatibility with sharepoint online services.
