1 This files describes API changes in /admin/*.
5 * The admin settings admin_setting_configselect and admin_setting_configmultiselect now support the optgroup tag.
6 Grouping of options can be created with this new tag.
7 For using it, the option parameters needs the Group names as indexes:
9 "Spain" => ["madrid" => "Madrid", "barcelona" => "Barcelona"],
10 "France" => ["paris" => "Paris", "marseille" => "Marseille"],
15 * Admin settings have been refined to better support right-to-left languages. In RTL,
16 most fields should not have their direction flipped, a URL, a path to a file, ...
17 are always displayed LTR. The admin setting will now best guess if they should be
18 RTLized based on their PARAM_* type. To override that guess, use
19 admin_setting::set_force_ltr(true/false).
