How can I configure below "Form builder js" in Magento 2.3.0 custom extension?
https://github.com/dobtco/formbuilder
I want to use this js in my custom Extension's form in the admin side.
Please try following way to add JS in admin:
Create file app/code/Vendor/Module/view/adminhtml/layout/adminhtml_system_config_edit.xml or add following code for JS in your custom module's admin layout XML
<?xml version="1.0"?>
<page xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:noNamespaceSchemaLocation="urn:magento:framework:View/Layout/etc/page_configuration.xsd">
<head>
<link src="Vendor_ModuleName::js/formbuilder.js"/>
</head>
</page>
You can put your formbuilder.js in following path.
app/code/Vendor/Module/view/adminhtml/web/js/formbuilder.js
Please check and let me know if any issue.
