uibuilder - Video 003 - Simple Form
This flow goes along with the YouTube video titled Simple, zero-code user input forms using uibuilder and Node-RED.
It demonstrates how to create a really simple, zero-code form using uibuilder and uib-element nodes. It also demonstrates how to cache the setup so that any newly connected clients or refreshed pages automatically get the form.
You don't need to have any coding skills to use this but you get access to the full range of HTML form capabilities. By default, the form is well laid out and is accessible for people with limited vision or movement.
Details on how to use the "Simple Form" type with the uib-element node are available in the uibuilder documentation: https://totallyinformation.github.io/node-red-contrib-uibuilder/#/elements/forms
