Hiding Sub Grid

Hi,

I am trying to hide a sub grid in a section(This section has four columns), there are multiple sub grids in this section but i want to hide just one of them.

When I run this line of JS: "Xrm.Page.getControl("LeadsCostConsultant").setVisible(false);" it hides all of the sub grids that are in the same row.

Any help will be great

Thanks
