Install

npm i sh-dynamic-form-builder

Install dependencies

Use bootstrap V5

npm install bootstrap --save

npm install bootstrap-icons --save

npm install sh-ordinal-numbers --save

Quick start

import { DynamicFormBuilderModule } from "sh-dynamic-form-builder";

@NgModule({
  imports: [DynamicFormBuilderModule],
})
export class AppModule {}

Import style and icon

In angular.json

"styles": [
    "src/styles.scss",
    "./node_modules/bootstrap/dist/css/bootstrap.min.css"

]

If Bootstrap icons don't work, you should import them in global style.

@import "~bootstrap-icons/font/bootstrap-icons";
