Hi @Ganasekhar-gif,

Thanks a lot for this PR! I'm not familiar with JS, so it is of great help :)

The filters seem to work well.
Just one remark, in the "Paradigm" dropdown menu, some tags seem to have been aggregated (for example Motor Imagery ERP SSVEP, see screenshot).
Is it intentional?

Hi @PierreGtch ,

Thank you for your feedback!
You're absolutely right — the aggregation of tags like "Motor Imagery ERP SSVEP" was not intentional. It was due to a parsing oversight in the dropdown filtering logic.

Thanks a lot for pointing that out — it really helped me catch and resolve the issue. I've now updated the code to properly split and display tags as individual entries. Please feel free to have another look and let me know if anything else needs adjustment!
