Describe the bug
I've defined my own component types with type specific drag-and-drop rules:
model: {
defaults: {
draggable: function (Candidate) {
console.log('WebCard target candidate',Candidate)
...
},
droppable: function (Candidate) {
console.log('WebCard drop candidate',Candidate)
...
},
but the configured functions are never invoked. Instead, dragging works without any constraints and dropping works into the wrapper element only.
A potentially important detail: my dragMode is set to 'absolute'

A first workaround which helps dropping components into other components:
- remove
dragMode:'absolute',fromgrapesjs.init({...}) - instead, add
dmode:'absolute',tomodel.defaultsof every component type you want to be draggable (and, perhaps, droppable)
Unfortunately, however, absolute positions are not recalculated after moving components into or out of containers...this makes the "feature" really difficult to use. Not mentioning, that sorting components into containers within the layer panel is tedious.
And, the draggable and droppable functions still do not get called.
In absolute mode, there is no concept of moving components inside/outside of other components. A component in absolute mode is only updated in style position, it's not moved in the DOM, that's why draggable/droppable does not make sense to work here.
Please @rozek avoid opening BUG issues if you don't have a full understanding of how things are supposed to be working, use Discussions for that matter.
Thanks for reporting this, @rozek.
The issue with draggable/droppable property functions not called while dragging appears to be a race condition or state management timing problem. This typically happens when component lifecycle events and DOM modifications overlap, creating an inconsistent state.
What to try:
- Add a setTimeout wrapper to ensure the DOM has settled:
setTimeout(() => {
// your operation here
}, 0);
-
Check initialization order β make sure components are fully loaded before you interact with them
-
Use the editor's event system β listen to completion events:
editor.on('component:mount', (component) => {
// safe to interact with component here
});
Recommended next steps:
- Test with the latest GrapesJS version if you haven't
- Provide a minimal reproducible example (CodeSandbox) β this helps the team identify the root cause faster
- Include GrapesJS version, browser, and console errors in your report
