 * This component is used as placeholder for empty panel, which represents an unset/empty value of something.
 * If this value is of multiple values (i.e. a an empty list), the most common operation to interact
 * with a list is `add`, otherwise use `modify`.
 *
 * When the the value is editable, supposed this is a list value, the placeholder can be interacted with in 2 ways:
 *  1. clicking on this placeholder to add a new item,
 *  2. (optional) or, dropping some material to create a new item and add it to the list
 *
 * When the value is read-only, show a placeholder to let user know the value is empty/blank/unset
