join
Joins the elements of a list. Joins the elements of the input list together, separated by the argument.
For example:
{{ value|join:", " }}
If the value is the list ["hello", "world"] then the output will be
"hello, world".
It is possible to use a special separator between the last two elements of the list,
for the list [ "Jan", "Piet", "Klaas" ] the following example:
{{ list|join:", ":_"or" }} }}
Gives as result:
Jan, Piet or Klaas
The spaces around the last separator are added by the filter.
