Feature summary (what you would like to be able to do):
The current MediaWiki-extensions-SecurePoll interface for ranked choice voting shows a series of drop-down menus to represent the first choice, second choice, etc. This task asks for creating an alternative UI in which each candidate is represented as a box, and the boxes can be dragged and re-ordered by the user.
Steps to reproduce (a list of clear steps to create the situation that made you report this, including full links if applicable):
(Section name is weird; "reproduce" is for something that exists, and this is request for a feature that doesn't exist)
Please see https://jqueryui.com/sortable/ as an example
Use case(s) (describe the actual underlying problem which you want to solve, and not only a solution):
When ranked-choice voting has many options and it is not allowed to have two candidates in the same rank, achieving this using drop-down menus can be difficult (you have to keep rechecking your other choices, unless you really have a clear picture of your ballot in your head or paper). The UI will allow users to more easily express a ranked choice vote.
