Grouping tags
In PREP, for tagging complex tags, where nesting is required, we need to group them under a parent tag. The grouping tag pane can be accessed by clicking on the + icon in left pane
After clicking on +, it will open up a list of grouping tags in the extreme left. You can select a single tag, to insert a grouping tag after it or you can select more than one tag to group them together inside of a grouping tag.
