I've implemented select box using bootstrap-select in angular 5. I've used latest version of Bootstrap select to make it work angular 5. But it throws below error.

bootstrap-select.js:1904 Uncaught TypeError: Cannot set property '_menu' of undefined

         <option>Mustard</option>
         <option>Ketchup</option>

Bootstrap-select v1.13.0-dev is compatible with Boostrap 4. You can find Compatible bootstrap-select files here Boostrap-select

Isue is that i am not loading required jquery and popper.min.js files into project directory. Also use non minified version of bootstrap select from repository code. I've solved this issue by adding above files.
