Still we need to manage multi checkbox column with template or is there any upgrade on this.
Thanks for the update
By default, in our EJ2 Grid, we have support only for single-column as checkbox column which is used to select the Grid rows. This was the default behavior of Grid. If you like to render multi-checkbox columns to perform selection, you can achieve your requirement by using column templates by rendering checkboxes as templates. Using that checkbox change event, you can perform the selection.
Before we start providing a solution to your query, we need more information for our clarification. So please share the below details that will be helpful for us to provide a better solution.
1) Please share your exact requirement scenario with a detailed description, of why would you like to render the multi checkbox selection column in the Grid.
2) Please share your complete use case scenario with a detailed description.
