From e13cbf9e27f688e59c868b7900a65d5133a4a753 Mon Sep 17 00:00:00 2001 From: Mihail Geshoski Date: Tue, 16 Jun 2020 09:42:08 +0800 Subject: [PATCH] MDL-60621 js: Add ability to set a modal to be scrollable or not With this change the modal can be configured to be scrollable or not. If enabled to be 'scrollable', the modal's body will become scrollable when the modal's height exceeds the browser's height. This is useful in cases where the content in the modal is quite large and extends the modal beyond the browser's height, which usually results in a bad UI. If 'scrollable' is not explicitely configured, it will be set as 'true' by default as in most cases it would be the expected behaviour. --- lib/amd/build/modal.min.js | 2 +-
