I want to remove the "update" button under the customer billing address section and implement the update functionality on the "place order" button in checkout page.

Successfully completed a half portion by combining billing-address.js with default.js and billing-address.html with checkout.html files.

File paths:

_vendor/magento/module-checkout/view/frontend/web/js/view/billing-address.js _vendor/magento/module-checkout/view/frontend/web/js/view/payment/default.js _vendor/magento/module-checkout/view/frontend/web/template/billing-address.html _vendor/magento/module-offline-payments/view/frontend/web/template/payment/checkmo.html

The scenario i followed:

First, rewrite the placeOrder databind code for multiple bindings on click event in checkout.html. Copy all code from billing-address.html and pasted into the checkout.html page where the place order button is placed. Erase the update & cancel button code and wrote the placeOrder button code instead of that.

Then wrote the update function in default.js and copy all the codes need to work this from billing-address.js.

Result:

When unchecked the box, a drop-down shows all the current addresses along with a new address option. Now, we can choose any of the address from the list and place the order. The address will be updated.

But when i choose the new address option from the drop-down list it didn't shows the address form.
