any html code for rendering formio custom component..
I have to render custom formio select drop down component in to my application.For that i created one js file like Select.js and i had taken the Select.js code from https://formio.github.io/formio.js/docs/class/src/components/select/Select.js~SelectComponent.html
and also i registered that component into my custom_formio.component.ts as
Formio.registerComponent('custom_formio', SelectComponent);
where custom_formio is the name of my component which having Select.js file and other ts and html and css files. and SelectComponent is the name of class name which is declared in Select.js file.
So i am getting confusion that which code i have to write in html to render select dropdown into my application
