How can I add more points such as number of tables, number of figures in " Enter metadata " tab during submission?

Thank you in advance!

Iā€™m not aware of any support ā€“ either in OJS or in a plugin ā€“ for metadata that describes the number of tables or figures in a publication. I think you would need to look into building your own custom plugin for that.
