Introduction
Select2 is a popular jQuery plugin used to enhance HTML select boxes with features such as searching, selecting, and displaying options in a user-friendly interface.
When Select2 is implemented inside a Bootstrap modal, the search input may sometimes stop working because of the way the Bootstrap modal handles focus and the tabindex attribute.
In this post we will fix the issue of Select2 search input not working in Bootstrap Modal.
Prerequisites
Before proceeding, ensure that:
- Bootstrap is implemented in the application.

Implementation
If you are implementing the Select2 plugin in a Bootstrap modal, first remove:
tabindex="-1"
and add:
style="overflow:hidden;"
After making this change, the Select2 search input should work correctly inside the Bootstrap modal.
Conclusion
