# Blocks
You can customize the initial state of the module from the editor initialization, by passing the following Configuration Object (opens new window)
const editor = grapesjs.init({
blockManager: {
// options
}
})
Once the editor is instantiated you can use its API and listen to its events. Before using these methods, you should get the module from the instance.
// Listen to events
editor.on('block:add', (block) => { ... });
// Use the API
const blockManager = editor.Blocks;
blockManager.add(...);
# Available Events
block:add
New block added to the collection. The Block is passed as an argument to the callback.
editor.on('block:add', (block) => { ... });
block:remove
Block removed from the collection. The Block is passed as an argument to the callback.
editor.on('block:remove', (block) => { ... });
block:remove:before
Event triggered before Block remove.
editor.on('block:remove:before', (block, remove, opts) => { ... });
block:update
Block updated. The Block and the object containing changes are passed as arguments to the callback.
editor.on('block:update', (block, updatedProps) => { ... });
block:drag:start
Started dragging block. The Block is passed as an argument.
editor.on('block:drag:start', (block) => { ... });
block:drag
The block is dragging. The Block is passed as an argument.
editor.on('block:drag', (block) => { ... });
block:drag:stop
Dragging of the block is stopped. The dropped Component (if dropped successfully) and the Block are passed as arguments.
editor.on('block:drag:stop', (component, block) => { ... });
block:category:update
Block category updated.
editor.on('block:category:update', ({ category, changes }) => { ... });
block:custom
Event to use in case of custom Block Manager UI (opens new window).
editor.on('block:custom', ({ container, blocks, ... }) => { ... });
block
Catch-all event for all the events mentioned above. An object containing all the available data about the triggered event is passed as an argument to the callback.
editor.on('block', ({ event, model, ... }) => { ... });
