How can I make a filter non user removable in list view?

Hi @ErpnextRaja,

Then you can use

// if sales user then hide
frappe.user.has_role('Sales User') == 1

// If not sales user then hide
frappe.user.has_role('Sales User') == -1

You can set conditions according to the scenario.

I hope this helps.

Thank You!
