Does the plugin custom fields supports shortcodes?
Yes and no.
The ACF plugin has a very simple shortcode which will display a simple value such as text. The repeater field will not work with this shortcode.
Every repeater contains different sub fields and the developer wants different HTML. This is why there is no generic shortcode. You will need to code the template to output the HTML you want. There are lots of tutorials and docs to follow for this
2. Can i import custom fields data using bulk import?
There is no import feature for the ACF plugin. The ACF plugin is a GUI layer for the native custom fields. This means it saves and reads data as a normal custom fields. That said, the repeater field saves it’s data in a very specific way which an import tool will not know.
