Sorry you are facing this issue, it would be my pleasure to help you.
Welcome to the Shopify community!
Thanks for your good question.
yes bundle is many customizations but i have suggestion you any free or paid app
There are many bundle apps in the store and we also have our own. It depends on what type of bundle options you want to have on your site. There are some that create new pages in your theme where users select from different options and they are all added to cart. Others like ours let you just create a normal product which has many components that are processed in the background when an order is made.
If your mean product bundles, there are several apps that let you create product bundles without any coding.
Ours does too and it has a Free plan with full features. Feel free to try it. Fast Bundle
