Renders the widget into the specified HTML element

Description

The box parameter can be either a DOM element or a CSS selector string. If it's a string, it will be converted to a DOM element using query selector. This method creates the widget's HTML structure, initializes event handlers, and sets up any necessary observers. It also triggers the 'render' event before and after rendering. // Render into an existing div let widget = new w2[widgetType]({ name: 'myWidget', // ... other options }); widget.render('#myContainer'); // Or render into a DOM element let container = document.getElementById('myContainer'); widget.render(container); The method returns the time taken to render the widget in milliseconds.
