From dfadc09501036dc0f1c2e85f096e1a535782e236 Mon Sep 17 00:00:00 2001 From: Martin Renvoize Date: Wed, 3 Nov 2021 14:37:11 +0000 Subject: [PATCH] Bug 29397: Add .kohaSelect select2 wrapper function This patch adds a kohaSelect wrapper function to simplify paging/infinite scrolling with select2 using the Koha RESTful api's. Invoke select2 select boxes as you normally would from JS, but instead of calling .select2(config) use .kohaSelect(config). If an 'ajax' property is defined in your config object, we wrap the transport such that responses include a pagination key as expected by select2.
