Description

Hello,

I am in need to select the columns by name instead of id or to retrieve the id of the column using its name and then selecting using the retrieved id.

I am referring to the following function:

grid.fields[id_of_the_column]

I am using this function inside the filterTemplate to dynamically create dropdown options on change.

the grid code works fine if I retrieve the column by id. However there are cases where the user can add optional columns to the grid and this breaks the code (all the id are shifted if the columns are added before the targeted ones).

Thank you for your time.

Research direction
Review the grid.fields implementation in jsgrid's source code, focusing on how fields are stored and accessed. The issue suggests that columns are currently accessed by numeric ID. To implement this feature, you could add a method to retrieve a column by its name property, or modify grid.fields to accept both IDs and names. Check the filterTemplate usage to understand the context. Look at existing issues or PRs for similar enhancements. Consider adding a mapping object from name to index for efficient lookup.
