Limit the number of times of block to be dropped
Hi @confettidc, you can try doing something like, have a counter variable and update it once a block of a type is added and remove the newly added block if the counter condition is satisfied. Do check the API Reference.

Hi @confettidc, you can try doing something like, have a counter variable and update it once a block of a type is added and remove the newly added block if the counter condition is satisfied.
editor.on('block:drag:stop', (comp, addedBlock) => {
// if the counter condition is satisfied then remove the component `comp`
// else check the type of 'addedBlock' If it matches with the one you want to limit and update the counter
})
Do check the API Reference.
Thanks for reporting this, @confettidc.
Great question about Limit the number of times of block to be dropped. The recommended approach with GrapesJS 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));
