JavaScript options : put only one "add" button at the bottom

Use add_at_the_end option set to false (default) to create an add for each element of the collection.

Use add_at_the_end option set to true if you want to have only one add button, located below the collection.

With the option set to false

This is the default behaviour, an add button is added for each element of the collection.

Value : a

Value : b

Value : c

With the option set to true

Only one add button is available, located at the bottom of the collection.

Value : a

Value : b

Value : c


Code used:

    <script type="text/javascript">

        $('.disabled-collection').collection();

        $('.enabled-collection').collection({
            add_at_the_end: true
        });

    </script>
