Slowness loading Jquery multi select in IE11
I am using a jquery/bootstrap multiselect with checkboxes in my application. I need to load around 15 state dropdowns during initial load. Its a user's preference page and so I need to check/uncheck the checkboxes in each dropdown based on user's preference(a backend service call) . IE freezes while loading these dropdowns. I have a loading indicator which also stops for some time. This works fine in chrome and firefox. I have a sample codepen link that recreates the issue ,which is below :
Any help with this issue will be appreciated !
Thanks!
