jquery-select2

问题 I have a Select2 Box, with tagging enabled to add new own tags. Selecting an existing option works without any problem (of any length). But some code prevents me from adding a new option longer than 2 characters long (just can't add more characters). See the JSFiddle <select class="form-control select2" multiple="multiple" id="employee-groups-select" name="employee[employee_group_ids][]"> <option value="4">Text1</option> <option value="1">Text2</option> <option value="3">Text3</option>

But how do I actually refer to the files - js and scss of select2 package in my app.blade.php ? 回答1: Run npm run watch , because keeps track of all changes in .js .
