You rewrite the etheme.js file and old file includes the fancy select code there that we don’t use anymore. I have updated etheme.js file but truly saying it’s not very good practice to overwrite the main js file of the theme.
Anyway, check now.
Thank you very much for updating it. Hopefully the theme update not overwrite these files. I will discuss your concern with technician who is doing customisation for us.
Is there any effect if we update theme in future?
If we make changes in etheme.js file that is overwritten in child theme you may face some issues after update. Everything depends on changes/fixes in theme js. That’s why it would be better if you can make customization without overwriting of the whole etheme.js but using your custom js file with changes that are related strictly to things that you want to change.
