How can I filter the options of a Link field in a Frappe form based on the value of another field in the same document?

Please take a look at this; I hope it works for you.

          // bind events
          
          frappe.ui.form.on("ToDo", {
          	onload: function (frm) {
          		frm.set_query("reference_type", function (txt) {
          			return {
          				filters: {
          					issingle: 0,
          				},
          			};
          		});
          	},
          	refresh: function (frm) {
          		if (frm.doc.reference_type && frm.doc.reference_name) {
          			frm.add_custom_button(__(frm.doc.reference_name), function () {

HI @Manav_Mandli @smitthakkar

Actually, from version-15 you can do it even without code …

Hope this helps.

Hii @avc

Thanks for sharing! Yes, I just checked and this works perfectly in version-15. Really helpful to know we can handle it without any custom code now
