Hello Andrey,

I have updated the code to enable multi-select with checkboxes and also activated the ‘Change All’ button to apply brand selection for all selected products in bulk edit. Please check the screen-recorded video for reference: https://excellentnumbers.com/temp_vid/Screencast%20from%202025-10-03%2011-12-51.mp4 .

Since this was the most important task, I haven’t yet reviewed your other suggestions and comments. I will check them and update you if needed.
