This is an absolutely simple package which beautifies the input fields a bit + uses select2 on every select input rendered on the site. It will make your life a bit easier.
composer require technodelight/magento1-admin-select2
First, reset your composer changes after the installation has been done
git reset composer.*
git checkout composer.*
Then add the following to .git/info/exclude
:
public/app/code/community/Technodelight/AdminSelect2
public/app/design/adminhtml/default/default/layout/technodelight_adminselect2
public/app/etc/modules/Technodelight_AdminSelect2.xml
public/skin/adminhtml/default/default/technodelight_adminselect2
