It is possible to delete multiple items at once using bulk actions.
First of all, go to the list that contains items that need to be deleted. This can be your invoices, your quotes, your products, interventions, or customers... Whatever the list, you just need to activate the grouped actions.
Go to a module with a list of items (customers, interventions, products...)
On the right, click on the columns
Check the grouped actions and click on "Show columns", there you will see a new column appear called " Bulk actions " with a ⚙️ icon.
Select all the items you wish to delete by ticking them, then click on the grouped action icon
• Check what you want to modify (in this case, the "Active" column)
• Click on "No".
