selection-list drawer page is displaying twice

You need to extends the field modules/Products/clients/base/fields/quote-data-relate and override the method _render this way:

_render: function() {
 if(this.model.get("quote_id") != undefined) {
 this._super('_render');
 } else if(this._rendered == false) {
 this._rendered = true;
 this._super('_render');
 }
},

Hi André Lopes,

Thanks for your solution. Its working fine for record view. But this.model.get("quote_id") and this._rendered both values are coming undefined for create view. So Product LineItem field is not displaying for create view page.

_render: function() {
           if(this.model.get("quote_id") != undefined) {
               this._super('_render');
           } else if(this._rendered == false  || this._rendered == undefined) {
               this._rendered = true;
               this._super('_render');
           }
},

I have added this._rendered == undefined condition and its working fine for create view also.

Thanks for your help.
