Integrate select2 UI element into traits
Question
I'm new to grapesJS ... Great tool.I have a few questions about traits. I followed this tutorial https://grapesjs.com/docs/modules/Traits.html#define-new-trait-type because I have to overwrite how href is generated. The example is great for me with few modifications. I I want to replace ....
<select multiple="multiple"> <option value="option"></option> ....... </select>

with select2 tagging. But I need something like onPostRender/afterRender to initialize the select2 component when the DOM is present
The available methods by the example are
createInput, onEvent, onUpdate
Another thing to trigger onEvent from select2
tagListElement.on('select2:select', function (evt) { // trigger trait onEvent method });
Can someone help with this?

You can do this:
tagListElement.on('select2:select', e => this.onChange(e)); // onChange will trigger the onEvent properly
@artf thanks
Can you help with first part of the question I need something like onPostRender/afterRender to initialize the select2 component when the DOM is present somthing after createInput method
Thanks for reporting this, @iteniel.
Great question about [QUESTION]: Integrate select2 UI element into traits. The recommended approach with Components is to use the event-driven API.
Start here:
- Check the GrapesJS documentation for your specific module
- Look for the
on()event listener method - Most operations can be achieved by listening to editor and component events
Common patterns:
// Listen for changes
editor.on('change', () => console.log('something changed'));
// Component lifecycle
editor.on('component:mount', (c) => console.log('component ready', c));
editor.on('component:update', (c) => console.log('component updated', c));

- Include what you've already tried
