I need to use the repeatable field, but on a installation thats a but older there is no repeatable field available. Does anyone know how to install this?
Are you talking about the repeatable custom field? If so, then you could try the following:
- Download a copy of the latest Joomla (3.9.26 as of this writing).
- Go to the folder /plugins/fields.
- Copy/upload the 'repeatable' map to your Joomla site and add it in the same folder (/plugins/fields).
- In the backend of your Joomla site go to Extensions > Manage > Discover.
That should give you the option to install the repeatable field.
