Key / Value fields provide an easy way to add non-structured information to your content.
This information is handled using key/value pairs that get stored in the content as a map than can then easily be displayed on a widget.
This field is helpful in creating a table of features for content.
Go to the Structure Manager and click on Add New Field.
Select Key/Value from the field types menu.
Once added, while editing content you can add key/value pairs to each piece of content.
These can also be deleted and / or reordered.
To display the key/value fields on a page, access the field by the variable name and then loop through the map returned.
#foreach($mapEntry in $content.mykeyvaluefield.map.entrySet()) $mapEntry.key : $mapEntry.value #end
