Idea Summary
Apex should introduce multiple value page item. In this Page item, label should be common, but the enterable field could be divided into multiple columns 2,3,4.
Use Case
we can use use this for range purpose e.g. if we are creating form and we have to set weight 34kg-55kg,
instead of using 2 page items we can use one page item, having common label and in first column we put 34kg and in 2nd 55kg.
Like we have multiple selection in LOV's we can have enterable as well.
