I use select2 in bootstrap tabs on Bootstrap Modal. One of the fields in the tabs does not work.
It works fine if it’s a field. But when I create another field in a tab, one of the fields doesn’t work.
My codes are below

In my project I’m using select2 for single selection and multiple selection dropdowns. I would like to extend only the MultipleSelection adapter for select2.

Unable to save and fetch the comma separated options into and from the DB(SQL). For example if a user select an option from the drop-down which contains comma or period operator(Ex:Vig,kumar mv) it didn’t work. If we have the space between the first and last names like attfirst attlast it works. Please look at the attached screenshot.

I found a problem to display select2 options to load categories or products and I tested with every method and it didn’t work. Even the options in the stackoverflow. Please check my code and suggest me the correct solution.

I have made changes in my code accordingly based on the answers given in this.
