Need to be able to create a link between records.

What can this be useful for?
For example, to create a link between recordings of several parts of the same game, book, movie, and so on.

Creating links between records should be unlimited.

The implementation can be as follows:
There is a record that has a special separate field with editing relationships.
In this field, you can select any of the created records to create a new relationship between them, and you can change this relationship from any record that is linked. And it is necessary in this field that the entries are not just added as they were selected, but that they can be moved exactly as they should be in order. And of course, after editing was finished and the record was saved, you need to display these links of records in the order in which they were set. And the records themselves in view mode should be clickable and when you click on any one, you will go to the corresponding record. And in the list, the entry that the user is viewing is highlighted as current.
