I'm using Select2 script to fill Dropdowns(Asp.net C#). Select2 is slow when opening its dropdown menu if the underlying select has a fair number of item. I have more than 15000 records in my dropdown. Is there any solution to reduce this slow?

I'm filling dropdown code behind. This is my script

<script type="text/javascript">
           $(".js-example-placeholder-single").select2({
               placeholder: "Select a state",
               allowClear: true
           });

       </script>

Solution 1

15,000 is way too many. If you look at the source you'll see why it is your browser is so slow. That's a lot for your browser to handle.

I suggest allowing them to filter.

Also, can you imagine how hard it would be for a user to find the 1 single option they want out of 15,000 choices? The scroll bar must be absolutely tiny and very hard to find what they need.

You should be honest with your client and tell them that a 15,000 drop down is unusable. Then suggest filtering.
